How do you didvide a fraction by a fraction?

To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)

How do you divide one third by a whole number?

Whole numbers as a fraction are equivalent to a/1. Division by a fraction is the same as multiplication by its reciprocal (the upside-down version of that fraction); for our whole number a = a/1, this would be 1/a. Thus, 1/3 divided by a is the same as 1/3 x 1/a = 1/3a.
