Learn how to subtract ordinary fractions: theory, steps and a practical example. Fractions with different (like) or unlike denominators

How to: Subtracting ordinary (simple, common) math fractions. Steps.

There are two cases regarding the denominators when we subtract ordinary fractions:

A. How to subtract ordinary fractions that have like denominators?

An example of subtracting ordinary fractions that have like denominators, with explanations

B. To subtract fractions with different denominators (unlike denominators), build up the fractions to the same denominator. How is it done?

An example of subtracting fractions that have different denominators (unlike denominators), step by step explanations
