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

Answer:

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

Step-by-step explanation:

Given information:

The weight of baby at birth = 7.25 lb

At the end of 8 months, the baby weighed $2\frac{1}{2}$ times its birth weight.

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

$2\frac{1}{2}=\frac{4+1}{2}=\frac{5}{2}$

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

$\text{Total weight}=7.25\times \frac{5}{2}$

$\text{Total weight}=18.125$

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

Answer 2

Simply multiply the baby's original weight, which is 7.25 lbs, by 2.5

7.25lbs x 2.5 = 18.125 lbs

The baby weighted 18.125 pounds at the end of 8 months.

Hope this helps and May the Force Be With You!
