Before we evaluate the expression, recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
5/4Ă·7/16 = 5/4* 16/7
When multiplying fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.
To multiply the given fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.
Let's multiply the first fraction by the reciprocal of the second.
9/11Ă·(- 20/21) = 9/11* (- 21/20)
When multiplying fractions, the product is equal to the product of the numerators over the product of the denominators.
Dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
- 8/3Ă·(- 5/18)=- 8/3* (- 18/5)
Now multiply the fractions. Remember that when we multiply two negative numbers, the product is positive.
