Question

A baby weighed 7.25 lb at birth at the end of 8 months , the baby weighed 2 1/2 times its birth weight. how many pounds did the baby weigh at the end of 8 month ?

Answer 1

The weight of baby at the end of 8 month is 18.125 lb.

Explanation:

Given information:

The weight of baby at birth = 7.25 lb

At the end of 8 months, the baby weighed
`2(1)/(2)` times its birth weight.

We need to find the weight of baby at the end of 8 month.

`2(1)/(2)=(4+1)/(2)=(5)/(2)`

The weight of baby at the end of 8 month is 5/2 times of its initial weight.

`\text{Total weight}=7.25* (5)/(2)`

`\text{Total weight}=18.125`

Therefore the weight of baby at the end of 8 month is 18.125 lb.
