If a number can be expressed as a terminating or repeating decimal then it is rational (and conversely). So -3 is rational.
The number 3 is a rational number (as is any integer).
-3 is a rational number
It is rational.The square root of 9 is 3 and it is a rational number
-3 is a rational number
10.01 is a rational number
1) Adding an irrational number and a rational number will always give you an irrational number. 2) Multiplying an irrational number by a non-zero rational number will always give you an irrational number.
3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
It is an integer. All integers are rational but not irrational. All rational and irrational numbers are real numbers.
It is a rational number as 9
Rational
RATIONAL , because you can convert it to a RATION (FRACTION). Method Let P = 0.272727.... Then 100P = 27.272727.... Subtract 99P = 27 (Note the decimals to infinity subtract to zero. P = 27/99 Cancel down by '9' P = 3/11 ( Which is a RATIO/rational). Since both '3' & '11' are prime numbers this will not cancel down any further. Hence 3/11 = 0.272727....
Negative three is a rational number.
