Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will teach you how to handle it on your own in the future.
First, let's look at our problem.
"A = L * W, solve for W."
This is basic algebra, but I will teach you how to tackle this problem, so you can do it on your own.
So, we have the following equation:
A = L * W
To solve for W, we need to get it alone on one side of the equation. Currently, it is not alone, but rather is being multiplied by L.
To isolate W, we need to perform the opposite order of operations on both sides of the equation.
A = L * W
Divide
both sides by L to isolate and solve for W.
W =

is our solution.
The following equation matches the answer choice "C".
Your answer is
"C."I hope this helps!

Here’s the step-by-step answer!
<span>In
the fairest school 20% are below 16 years old
1/3 are teachers which is equals to = 21
Let’s start solving:
=> 1/3 of 100% = ( 100 / 3 = 33.33% )
thus 33.33% = 21
=> 21 x 3 = 63, is the total number of people in the school.
Let’s try solving the number of people below 16 years old
Then there are 20% of it:
=> 63 * .20 = 12.6
Thus, there are around 13 people who are 16 years old younger.</span>
