Question

Mia's new puppy weighed 3 1/5 pounds at 4 weeks old. At 16 weeks old, the puppy weighed 9 1/7 pounds. By what factor did the puppy's weight increase

during that period? Write your answer as a mixed number.​

Answer 1

By a factor of 2 6/7.

Explanation:

That would be 9 1/7 divided by 3 1/5

= 64/7 / 16/5 Invert the dividing fraction:

= 64/7 * 5/16

= 4/7 * 5

= 20/7

= 2 6/7.
