72.28 is what percent of 142.87 - 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 142.87 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 142.87, so we can write it down as 100%=142.87.
4. We know, that x% equals 72.28 of the output value, so we can write it down as x%=72.28.
5. Now we have two simple equations:
1) 100%=142.87
2) x%=72.28
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%=142.87/72.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72.28 is what percent of 142.87

100%/x%=142.87/72.28
(100/x)*x=(142.87/72.28)*x       - we multiply both sides of the equation by x
100=1.976618705036*x       - we divide both sides of the equation by (1.976618705036) to get x
100/1.976618705036=x
50.591446769791=x
x=50.591446769791

now we have:
