Mathnasium #MathTricks: Number Sense (Division Part 1)

By Mathnasium | May 25, 2022

Welcome to Mathnasium’s Math Tricks series.

With these patterns, we can develop “tricks” to compare them. Today we are using our knowledge of the parts of a fraction to identify the biggest and smallest fractions with common denominators.
