12.75 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 12.75 of the output value, so we can write it down as x%=12.75.
5. Now we have two simple equations:
1) 100%=132
2) x%=12.75
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%=132/12.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.75 is what percent of 132

100%/x%=132/12.75
(100/x)*x=(132/12.75)*x       - we multiply both sides of the equation by x
100=10.352941176471*x       - we divide both sides of the equation by (10.352941176471) to get x
100/10.352941176471=x
9.6590909090909=x
x=9.6590909090909

now we have:
12.75 is 9.6590909090909% of 132
