Question

A baby weighs 18 pounds at her four month appointment. Six months later she weighs 24 pounds. By what percentage did the baby's weight increase?

Answer 1

Answer: the percentage is 33.33%

Explanation:

The initial weight is 18 pounds and is what we will define as the 100%.

The later weight is equal to 24 pounds.

The direct difference is 24 pounds - 18 pounds = 6 pounds, now, we want to know wich percentage the 6 pounds represent:

the percentage of the weight increase equal to the fraction between the difference and the initial weight:

X = (6/18)*100% = 33.33%

So the weight of the baby increase an 33.33%

Answer 2

The baby's weight increase 33.33%

Explanation:

we know that

A baby weighs 18 pounds at her four month appointment

Six months later she weighs 24 pounds

so

18 pounds represent the 100%

using proportion

Find out what percentage represent the increase (24-18)=6 pounds

Let

x ----> the percentage increase

`(18)/(100\%)=(6)/(x)\\\\x=100\%(6)/18\\\\x= 33.33\%`
