Question

Last year, Sarah used 16 ½ gigabytes of data on her cell phone. How many gigabytes did Sarah use each month?

Answer 1

Answer:

1 $\frac{3}{8}$ gigabytes

Step-by-step explanation:

We are provided the number she used in a year, to find the average number she used in a month, we need to divide the total by 12.

16 1/2= 33/2

$\frac{33}{2} /12$

Dividing is the same as multiplying by its reciprocal

$\frac{33}{2}$ × $\frac{1}{12}$

=$\frac{11}{8}$

We can then convert that back into a mixed number.

$\frac{11}{8}$=1 $\frac{3}{8}$

She used 1 $\frac{3}{8}$ each month.
