10. There are 355 students at Median Middle School. If there 8% of the students were absent on Tuesday, how many students were a
Setler79 [48]

To solve this question, we simply need to divide the total amount of students by 8% to find out how many students were absent and how many were present.

However, we can't simply multiply it by 8%, so we need to turn that into a decimal.

8% - 0.08

<em>Multiply:</em>

<em>355 x 0.08</em>

<em>= 28.4</em>

<em>Round:</em>

<em>28 kids were absent</em>

<em>Subtract:</em>

<em>355 - 28</em>

<em>= 327</em>

<em />

<em>This means that </em><em>28 kids were absent</em><em>, and </em><em>327 kids were present</em><em>.</em><em> </em>
