x has to equal 1. 3/10 + 1/5 = 1/2
the equation is now 1/2 + x = 1 1/2x
x = 1
1 1/2 = 1 1/2
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>

You have to find 80% of 20.
Since 80% is equal to 0.8, you multiply 20 by 0.8 to get 16
