Question

7 jacklyn’s baby brother goes through 18 diapers every 4 days. at this rate, how many diapers will jacklyn’s baby brother go through

diapers in 28 days. write a proportion and solve.

Explanation:

Step1: Find the number of 4 - day periods in 28 days

To find how many 4 - day periods are in 28 days, we divide 28 by 4. So, $\frac{28}{4}=7$.

Step2: Calculate the number of diapers in 28 days

Since in each 4 - day period the baby uses 18 diapers, and there are 7 such periods in 28 days, we multiply the number of diapers per 4 - day period by the number of 4 - day periods. That is $18\times7 = 126$.

Answer:

126
