if you have mixed numbers you make them into improper fractions before you multiply

No.

You don't.

someone help me on mathh)"

False.

First change the mixed numbers into improper fractions by multiplying the denominator and the whole number and add the product to the numerator in the mixed numbers and then multiply the numerators and the denominators and divide the numerator by the denominator of the product.

Simplicity of calculation

Change each mixed fraction to an improper fraction. Do this by multiplying the denominator by the whole number next to the fraction and then adding the numerator to the product you get. Once you do this, multiply fractions normally.

No. The commutative and associative laws are valid for any real numbers.

First you change them into improper fractions. Then you multiply the numerator and the denamanator straight across. ;)

No it’s can not be a number less than one because a number times one get you the same number

Fractions and decimals are usually rational numbers. Besides, multiplying rational and irrational numbers is also similar.

It is not as helpful when multiplying very small numbers because the numbers are going to be very east to answer. That is why estimating is not as helpful when multiplying very small numbers.

So that you can get your answer more faster and you don't need to do a lot of work

The result of multiplying numbers is called the product.

It depends on the numbers. For example, dividing by 1 1/2 (one and a half) is exactly the same as dividing by 3/2, since both represent the same number.In general, if you divide by a larger number, the result will be less.

Mixed numbers cannot be turned into proper fractions, but they can be made into improper fractions by multiplying the integer (# on the side) by the denominator (bottom), and then adding that number to the numerator (top).

no

It is not. When multiplying two whole numbers you need not be concerned about placing the decimal point in the answer.

There is no need to borrow when multiplying. You need to carry numbers when multiplying but not borrow.

You can convert a mixed number to an improper fraction by multiplying the denominator by the whole number, adding the numerator and putting that total over the denominator. 2 and 3/4 = 4 x 2 + 3 = 11/4

why does multiplying numbers by ten move the decimal point to the right

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.

prime numbers

Multiplying numbers in scientific notation is easier when the numbers are very, very large or very, very small. Multiplying 0.000000000385 x 0.0000000474 is a pain. Multiplying 3.85 x 10-10 x 4.74 x 10-8 is not.
