418.75 is what percent of 502.5 - 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 502.5 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 502.5, so we can write it down as 100%=502.5.
4. We know, that x% equals 418.75 of the output value, so we can write it down as x%=418.75.
5. Now we have two simple equations:
1) 100%=502.5
2) x%=418.75
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%=502.5/418.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 418.75 is what percent of 502.5

100%/x%=502.5/418.75
(100/x)*x=(502.5/418.75)*x       - we multiply both sides of the equation by x
100=1.2*x       - we divide both sides of the equation by (1.2) to get x
100/1.2=x
83.333333333333=x
x=83.333333333333

now we have:
418.75 is 83.333333333333% of 502.5
