Exercise 2 Page 97

Multiply both the numerators and the denominators.

6/25

Practice makes perfect
When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product!
3/10*4/5
3* 4/10* 5
12/50
Since 12 and 50 have a common factor, we can simplify our fraction by dividing both the numerator and the denominator by 2.
12/50
12Ă· 2/50 Ă· 2
6/25
There are no more common factors between the numerator and the denominator. Also, because the denominator is greater than the numerator, we cannot write the quotient as a mixed number. This means that the answer is in the simplest possible form.

Checking Our Answer

We can check our answer by finding the product using a calculator. However, most calculators will give the product as a decimal number. Because our answer is a fraction, we need to compare the product of the original fractions to the decimal that is equivalent to the final product that we found. First, let's find the decimal form of our product.

Now we will find the product of the fractions using the calculator. Remember to use parentheses around each of the fractions so that the order of operations is performed correctly! Calculators cannot read our minds, unfortunately.

Because the calculator found the same decimal for both calculations, we know that our answer was correct!
