Not clear what you mean. 40 millimeters are 4 centimeters.

What is 3 times 10 to the fourth power times 7 times 10 to the fifth power

Such large numbers are best written in scientific notation. In this case, 3 x 1014.

34.5 is RATIONAL.

Irrational numbers are those were the decimals go to infinity AND there is no regular order in the decimal numbers.

Definitively an Irrational Number CAnnot BE CONVERTED TO A quotient/ratio/frACTION

pi = 3.141592.... is the most well known irrational number.

So

34.5 is rational

34.55555..... is rational (gOES TO INFINITY ; numbers in regukar order).

34.565656.... is Rational (Goes to infinity ; numbers in regulkar order).

et seq.,

The dots after the number mean it continues to infinity .

However,

34.25865414..... is Irrational . Because there is no regular order in the decimal digits.

1.5 hours is one hour and 30 minutes.

Square feet can't be converted to feet. Square feet measure area, while feet measure length.

10 to the power of 1000 is called a "googol." It represents a 1 followed by 1000 zeros, which is an extremely large number. The term "googol" was coined by mathematician Edward Kasner in the early 20th century and is often used to illustrate the concept of very large quantities.

what is ten times 3 forths

To simplify the fraction 36 over 30, find the greatest common divisor (GCD) of the numerator and the denominator, which is 6. Dividing both the numerator and the denominator by 6, we get 6 over 5. Therefore, 36 over 30 in simplest form is 6/5.

10100 = 10,100

Oh, dude, getting a million stickers on First in Math is as easy as eating a whole pizza by yourself... if you're into that sort of thing. Just keep solving those math problems like it's your job (but not really, because who wants math to be their job?) and before you know it, you'll be drowning in stickers. Like, seriously, you might need a bigger backpack for all those bad boys.

Yes, when any number is multiplied by a decimal, as long as the decimal is less than 1, the product is smaller that that number (assuming we are just dealing with positive numbers)

An example is 5 times .4, which equals 2. 2 is less than 5.

Another example, this time where both numbers are decimals, is .3 times .1 which equals .03. .03 is smaller that both .3 and .1.

The reason it gets smaller is because by multiplying by a decimal, you are trying to get a fraction of the number, which will always be less than that number. For example, 3 times .5 = 1.5. Here, the result is a fraction (1/2) of three.

To determine if an estimate is an overestimate or an underestimate, compare the estimate to the actual value or a more accurate reference point. If the estimate is greater than the actual value, it's an overestimate; if it's less, then it's an underestimate. Additionally, consider the methods used for estimation—if they generally involve rounding up or using conservative assumptions, they may lean towards overestimation, while rounding down or being overly cautious may lead to underestimation.

0.6 is a decimal. As a proper fraction it is 3/5.

77,777 can be shown as 38,888+38,889 = 77,777

You can use properties such as the distributive property, associative property, and commutative property to write equivalent expressions. For example, the distributive property allows you to expand or factor expressions, like rewriting (a(b + c)) as (ab + ac). The commutative property enables you to change the order of terms, such as (a + b) becoming (b + a), while the associative property lets you regroup terms, such as ((a + b) + c) being rewritten as (a + (b + c)). By applying these properties, you can create different but equivalent forms of the same expression.

The only number is 13 X 1 or 1 X 13... If your trying to get an equation to equal 13 you have to add up to get to 13.

Example- 9+4x1= 13

10000 boxes to get 10000 boxes!

The simplest form of 25 over 35 is 5/7, by simply divide both number by 5.

To determine the number of 2-meter tall people in the world, we would need to consider the average height distribution of the global population. The probability of an individual being exactly 2 meters tall would be quite low, as this height is significantly above the global average. However, with the current global population estimated at around 7.9 billion, we could estimate the number of individuals around 2 meters tall to be a very small fraction of that total.
