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.​

Respuesta :

Answer:

By a factor of 2 6/7.

Step-by-step 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.
