142.3 is what percent of 502 - 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 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, so we can write it down as 100%=502.
4. We know, that x% equals 142.3 of the output value, so we can write it down as x%=142.3.
5. Now we have two simple equations:
1) 100%=502
2) x%=142.3
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%=502/142.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 142.3 is what percent of 502

100%/x%=502/142.3
(100/x)*x=(502/142.3)*x       - we multiply both sides of the equation by x
100=3.5277582572031*x       - we divide both sides of the equation by (3.5277582572031) to get x
100/3.5277582572031=x
28.346613545817=x
x=28.346613545817

now we have:
142.3 is 28.346613545817% of 502
