15.5 is what percent of 132 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 132 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 132, so we can write it down as 100%=132.
4. We know, that x% equals 15.5 of the output value, so we can write it down as x%=15.5.
5. Now we have two simple equations:
1) 100%=132
2) x%=15.5
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%=132/15.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.5 is what percent of 132

100%/x%=132/15.5
(100/x)*x=(132/15.5)*x       - we multiply both sides of the equation by x
100=8.5161290322581*x       - we divide both sides of the equation by (8.5161290322581) to get x
100/8.5161290322581=x
11.742424242424=x
x=11.742424242424

now we have:
15.5 is 11.742424242424% of 132
