1. What do you notice? When you multiply a fraction by a whole number, you are adding that fraction to itself the number of times indicated by the whole number. The result is a new fraction where the numerator is the product of the whole number and the original numerator, and the denominator stays the same. You can then simplify or convert it to a mixed number if needed.
2. Now try these:
3 × 2/5 = 6/5 = 1 1/5
3.
4 × 4/7 = 16/7 = 2 2/7
4. 3 × 2/7 = 6/7
5. 4 × 3/5 = 12/5 = 2 2/5
6. 5 × 5/8 = 25/8 = 3 1/8
7. 6 × 7/10 = 42/10 = 4 1/5
