Comparing Like Fractions
We can compare like fractions by comparing their numerators. Fractions with bigger
numerators are bigger.

Example 11: Harshita and Muskan were making a model for their project. Harshita made
3 of the model and Muskan made 2 of it. Who made the bigger part of the
5 5
model?

Solution: 3 and 2 are like fractions because their denominators are same. So, to
5 5
compare the fractions we compare their numerators.

Since 3 > 2, 3 > 2 .
5 5
Thus, Harshita made the bigger part of the model.
