142.5 is what percent of 253.5 - 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 253.5 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 253.5, so we can write it down as 100%=253.5.
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%=253.5
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%=253.5/142.5
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 253.5

100%/x%=253.5/142.5
(100/x)*x=(253.5/142.5)*x       - we multiply both sides of the equation by x
100=1.7789473684211*x       - we divide both sides of the equation by (1.7789473684211) to get x
100/1.7789473684211=x
56.213017751479=x
x=56.213017751479

now we have:
142.5 is 56.213017751479% of 253.5
