Simple fraction addition
Test your understanding of simple fraction addition by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's add two thirds and two fifths
🎙️
First, find the common denominator. The LCM of 3 and 5 is 15
🎙️
So we can convert both fractions to denominators of 15. We now have ten 15ths plus six 15ths
🎙️
Since the denominator is the same, we can just add the numerator. That gives sixteen 15ths
🎙️
Let's simplify that to 1 and one 15th as our answer
