This document provides steps for adding fractions, beginning with checking if the fractions have the same denominator. If so, add the numerators and keep the denominator. If not, a new denominator is needed, called the least common multiple (LCM), which is the smallest number that is a multiple of both denominators. It gives examples of finding the LCM and provides tricks for determining it such as whether the denominators are prime numbers or multiples of each other.

1. FRACTIONS ADDITION FOLLOW THE STEPS

2. DO THEY HAVE THE SAME DENOMINATOR? ? YES NO ADD THE NUMERATORS AND KEEP THE SAME DENOMINATOR WE CAN NOT ADD THE NUMERATORS! WE NEED A NEW DENOMINATOR …
