Question

A newborn baby's weight increased by 50% in one month. If the baby weighed 8 pounds at birth, how much did it weigh one month later? Also can you please explain the process on how to do this, Thanks!

4 lb
10 lb
12 lb
16 lb

Answer 1

It would weigh 12 lbs because 50% of 8 is 4 and 4 + 8 = 12 lbs.

Answer 2

12 lb

Explanation:

The baby weighed 8 pounds at birth which means this was the babys original weight. If the baby's weight increased by 50%, it will be 50% of 8 pounds plus the 8 pounds. The percentage 50% iin fraction form is:

`50/100`

50% of 8 pounds is:

`=(50/100)\cdot{8}=400/100=4`

To get the final weight, we must add 4 to the original weight of 8 pound:

`4+8=12`
