12.7 is what percent of 32 - 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 32 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 32, so we can write it down as 100%=32.
4. We know, that x% equals 12.7 of the output value, so we can write it down as x%=12.7.
5. Now we have two simple equations:
1) 100%=32
2) x%=12.7
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%=32/12.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.7 is what percent of 32

100%/x%=32/12.7
(100/x)*x=(32/12.7)*x       - we multiply both sides of the equation by x
100=2.5196850393701*x       - we divide both sides of the equation by (2.5196850393701) to get x
100/2.5196850393701=x
39.6875=x
x=39.6875

now we have:
12.7 is 39.6875% of 32
