Exercise 21 Page 323

Multiply the first fraction by the reciprocal of the second fraction.

5/12

Practice makes perfect
To divide fractions, multiply the first fraction by the reciprocal of the second fraction. 1/4÷3/5=1/4*5/3 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!
1/4*5/3
1 * 5/4 * 3
5/12

Checking Our Answer

We can check our answer by substituting the obtained result for the first fraction and multiplying it by the second fraction. The product we get should be the dividend of the given expression.
5/12 * 3/5 ? = 1/4
5 * 3/12 * 5 ? = 1/4
15/60 ? = 1/4
15/15/60/15 ? = 1/4
1/4 = 1/4 ✓
Since both sides are the same, we know that our answer was correct!
