# Is 99 a rational number?

A rational number is any number that can be written as a fraction, so yes, 99 is indeed a rational number.

### Is the number 99 rational or irrational?

99 is an irrational number! rational number is the one which can be wrriten in terms of ratios of two numbers! * * * How about 99 = 198/2 = 293/3 = 396/4? Every whole number is a rational number, of course, including 99.

### Is 99 divided by 82 a rational number?

Any integer divided by any other integer is a rational number. See the definition of rational numbers.

### Is this a rational number 0.323232?

A rational number is a number that can be expressed as the division a/b where a and b are both integers. In this case 0.323232.... is a recurring decimal, and so is rational, as all recurring decimals are rational. This can be proved in the following way: 0.323232... x 100 = 32.323232... 0.323232... x 100 - 0.323232... = 32 0.323232... x 99 = 32 0.323232... = 32/99 Therefore 0.323232... is a rational number.

### Is 0.323232 a rational number?

A rational number is one which can be expressed by a division of a/b where both a and b are integers. In this case, we have a repeating decimal. All repeating decimals are rational numbers, and so we can say 0.323232.... is a rational number. The proof is as follows: 0.323232... x 100 = 32.323232... 0.323232... x 100 - 0.323232.... = 32 0.323232... x 99 = 32 0.323232... = 32/99 Thus 0.323232.... can be expressed… Read More

### Is 0.131313 a rational number?

0.13131313 is a rational number, as it's a recurring number, and all recurring numbers are rational. To prove this, you first multiply by 10 until the decimal part of the number is the same. In this case, 0.13131313...x100=13.13131313.... Then you take off the original number 0.131313...x100 - 0.131313... = 13 Now you can simplify the left hand side 0.131313...x99=13 And divide both sides by 99, to get 0.131313....=13/99 So the original number can be expressed… Read More

### Is 0.58585858 a rational number or an irrational?

If that is a terminating decimal: 0.58585858 = 58585858/100000000 = 29292929/50000000 And thus a rational number If it's a recurring decimal: 0.58585858... = 58/99 And thus a rational number

### Is the the decimal 0.64 repeating rational or irrational?

Irrational: it amounts to roughly 9.949874371

### What are rational numbers that are not integars?

Integers are whole numbers, with no fraction or decimal part. Rational numbers are numbers that can be expressed in the form a/b where a and b are both integers. Thus 1/2 is a rational number, but not an integer. 0.34343434... is a rational number (as it can be expressed as 34/99) but is not an integer.

### Is 0.36 repeating irrational?

No. It is rational: 0.363636... = 36/99 = 4/11 Any decimal which terminates or ends in a repeating sequence of digits is a rational number.

### Is - 0.29292929292929 a rational number or an irrational number?

Any terminating decimal or repeating decimal is a rational number. -0.29292929292929 is either a terminating decimal of the fraction -29292929292929/100000000000000 or meant to be a recurring decimal (0.2929...) with the '29' recurring forever of the fraction 29/99 Either way, it is a rational number.

### Is 0.62 repeating a rational number?

Yes because if need be it can be expressed as a fraction in the form of 62/99

### Is 0.2323232323 a rational number?

Yes, because it has a finite number of digits and can therefore be written as a ratio of integers. If you meant to put a "..." at the end, it would still be rational. Let x = .232323... 100x = 23.232323... 100x - x = 23.232323... - x 99x = 23.232323... -.232323... 99x = 23 x = 23/99 .232323... = 23/99

### Is 0.676767 a rational number?

Yes. Rational numbers are those number which can be represented as fractions. All decimals which terminal or end in recurring digits can be represented as fractions and are rational numbers. If you mean the exact decimal 0.676767 it is 676767/1000000 as a fraction. If you mean the recurring decimal 0.676767... it is 67/99 as a fraction.

### What type of number is 10 divided by 3?

A rational number. A rational number. A rational number. A rational number.

### Is pi rational?

A rational number is a number that can be expressed as one integer divided by another. Decimals can only be expressed in such a way if they are repeating. For example 0.4646464646... is 46/99 and 0.333333.... is 1/3. Because pi is a non repeating decimal, it cannot be expressed in this way. Thus it is an irrational number.

There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.

### Is a rational number always a rational number?

As much as, in these days of uncertainty, anything can be anything. As long as the constraints of a rational number are kept to, a rational number will always remain a rational number.

### Which number can be multiplied to a rational number to explain that the product of two rational numbers is rational?

It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.

### Why the product of nonzero rational number and a rational number is an irrational?

Actually the product of a nonzero rational number and another rational number will always be rational. The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)

### How is a rational number that is not an integer different from a rational number that is an number?

A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.

### Can you multiply an irrational number and a rational number to get a rational number?

Yes, but only if the rational number is 0.

### Can a rational number be multiplied by an irrational number and equal a rational number?

Only if the rational number is 0.

### How do you determine if eleven out of twenty is a rational or irrational number?

All whole numbers are rational. Any rational number divided by another (non-zero) rational number is a rational number.

### Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?

The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.

### Classify the following number as rational or irrational 0.444444?

The number 0.444444 is a rational number. It is equivalent to 111111/250000, which, by definition of rational numbers, is rational. The number 0.444... (repeating) is also rational because it can be represented by the fraction 4/9. The number 0.444444 is a rational number because a rational number is a nnumber that can be expressed in the form of a fraction.

### Is a rational number is a rational expression?

Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.

### Is 161616 a rational number?

A rational number is a number that can be represented as a fraction: numerator/denominator. Any whole number is rational, since {number} = {number}/1. Since 161616 is a whole number, it is rational.

### Is 0.74362991 is a rational number?

That is a rational number. Any numbers that are not rational (irrational) are either repetitive such as 0.3333333.......... or are surds. Since this number is not one of them, it is a rational number.

### If x is a rational number and y is a rational number than is x plus y rational?

If both numbers are rational then x plus y is a rational number

### Is 0.636363 an rational number?

yes... r= 0.63636363... 100r= 63.636363... 100r - r= 99r 99r = 63 r= 63/99 hope this helps!

### Does there exist an irrational number such that its square root is rational?

No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be… Read More

### Is a rational number minus a rational number a rational number?
