Comparing Fractions: Steps and Strategies

In this video, Mr. J explains how to compare fractions by finding common denominators and using benchmark fractions. He demonstrates four comparisons: 3/8 vs. 13/16, 2/12 vs. 8/9, 3/4 vs. 6/8, and 8/10 vs. 17/20. The video emphasizes the importance of common denominators and benchmarks like 1/2 to determine which fraction is greater or if they are equal.

What is the first step in comparing fractions?

• Multiply the fractions

• Find a common numerator

• Find a common denominator

• Add the fractions
