Question

Greta uses 4 ounces of pasta to make 4/5 of a serving of pasta. How many ounces of pasta are there per serving?

Answer 1

Take 4oz. In a fraction. 4/1. Divide 4/1 by 4/5. When your dividing fractions the divisor ( the second fraction) is flipped.

So then it will be 4/1 multiplied by 5/4 which is 20/4 which is 5. So 5 Oz. Per serving.
