Answer:
C is the correct answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 128 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 128, so we can write it down as 100%=128.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=128
2) x%=36
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=128/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 36 is what percent of 128
100%/x%=128/36
(100/x)*x=(128/36)*x - we multiply both sides of the equation by x
100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x
100/3.55555555556=x
28.125=x
x=28.125
36 is 28.125% of 128
