142.5 is what percent of 417.5 - 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 417.5 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 417.5, so we can write it down as 100%=417.5.
4. We know, that x% equals 142.5 of the output value, so we can write it down as x%=142.5.
5. Now we have two simple equations:
1) 100%=417.5
2) x%=142.5
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%=417.5/142.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 142.5 is what percent of 417.5

100%/x%=417.5/142.5
(100/x)*x=(417.5/142.5)*x       - we multiply both sides of the equation by x
100=2.9298245614035*x       - we divide both sides of the equation by (2.9298245614035) to get x
100/2.9298245614035=x
34.131736526946=x
x=34.131736526946

now we have:
142.5 is 34.131736526946% of 417.5
