Question

a babay weighs 8 & 1/4 pounds at birth two weeks later she weighs 8 & 7/8 how much weight did the baby gain

Answer 1

⅝ pounds

Explanation:

Weight at birth = 8¼ pounds

Weight after two weeks = 8⅞ pounds

`Weight \: gain \\ = Weight \: after \: two \: weeks - Weight \: at \: birth \\ = 8 (7)/(8) \: pounds - 8 (1)/(4) \: pounds \\ = (8 (7)/(8) \: - 8 (1)/(4)) \: pounds \\ = (8 (7)/(8) \: - 8 (2)/(8)) \: pounds \\ = ( (7)/(8) \: - (2)/(8)) \: pounds \\ = (5)/(8) \: pounds`
