Multiplying Fractions by Whole Numbers — Easy Worksheet 1
Grade 5 · MathSheets Name: ____________________ Date: __________
Answer each question. The same kind of product comes in different shapes. Write fractions in simplest form, as a mixed number if greater than 1.
How to solve
Multiply the numerator by the whole number and keep the denominator: 23 × 5 = 103 = 3 13. It can be quicker to divide first: 34 × 8 → 8 ÷ 4 = 2, then 3 × 2 = 6. Simplify the answer, and for a mixed number × a whole number change it to an improper fraction first (2 13 = 73, so 2 13 × 4 = 283 = 9 13).
Example
13 × 2 = ___
Answer: 23
