Question

Jarett's puppy weighed 3 3/4 ounces at birth at one week old, the puppy weighed 5 1/8 ounces at two weeks old the puppy weigh at three weeks old?

Answer 1

well, i find it helps to turn the fractions into decimals.
3 3/4 = 3.75
5 1/8 = 5.125

so now subtract:
5.125 - 3.75 = 1.375

so that means it weighs 1.375 ounces more each week

so then take the second week (5.125) and add on 1.375

5.125 + 1.375 = 6.5

now to convert that into a fraction (lowest terms) it would be:
6 1/5 ounces

Therefore,
Jarett's puppy will weigh 6 1/5 ounces at three weeks old.

Hope this helps and ave a great day! :D
