a baby weighed 7 pounds 7 ounces at birth and 8 1/8 pounds at her first chekup how many ounces had the baby gained

Respuesta :

One pound 7 ounces I think is the answer
so first:
7 ounces = 7/16   1/8 = 2/16 = 2 ounces
then:
8 pounds 2 ounces - 7 pounds 7 ounces = 11 ounces 
130 ounces - 119 ounces = 11 ounces
11 ounces is your answer
