What does it mean to decompose a fraction?

Back

To decompose a fraction means to break it down into smaller fractions that add up to the original fraction. For example, 3/4 can be decomposed into 1/4 + 1/4 + 1/4.

What is a unit fraction?

Back

A unit fraction is a fraction where the numerator is 1 and the denominator is a positive integer. For example, 1/3 and 1/5 are unit fractions.
