412.5 is what percent of 542 - 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 542 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 542, so we can write it down as 100%=542.
4. We know, that x% equals 412.5 of the output value, so we can write it down as x%=412.5.
5. Now we have two simple equations:
1) 100%=542
2) x%=412.5
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%=542/412.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 412.5 is what percent of 542

100%/x%=542/412.5
(100/x)*x=(542/412.5)*x       - we multiply both sides of the equation by x
100=1.3139393939394*x       - we divide both sides of the equation by (1.3139393939394) to get x
100/1.3139393939394=x
76.107011070111=x
x=76.107011070111

now we have:
412.5 is 76.107011070111% of 542
