📚 Topic Summary
Unit fractions are fractions with a numerator of 1. When comparing unit fractions, the fraction with the smaller denominator is actually the larger fraction. This is because the whole is being divided into fewer parts, making each part bigger. Visualizing these fractions with diagrams can make comparing them much easier! For example, 1/2 is larger than 1/4 because a whole divided into 2 parts has bigger pieces than a whole divided into 4 parts.
