Fraction of a number across the grades

4th grade

Fraction of a number worksheets for fourth grade ask questions like 1/4 of 20, leaning on unit fractions, one part at a time. Divide by the denominator to find that single part; answers come out whole every time.

5th grade

Fifth grade moves to any fraction of a number: 2/3 of 18, 3/5 of 40. Divide by the bottom, multiply by the top, and the answers still come out whole.
