58 is what percent of 8040 - 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 8040 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 8040, so we can write it down as 100%=8040.
4. We know, that x% equals 58 of the output value, so we can write it down as x%=58.
5. Now we have two simple equations:
1) 100%=8040
2) x%=58
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%=8040/58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 58 is what percent of 8040

100%/x%=8040/58
(100/x)*x=(8040/58)*x       - we multiply both sides of the equation by x
100=138.62068965517*x       - we divide both sides of the equation by (138.62068965517) to get x
100/138.62068965517=x
0.72139303482587=x
x=0.72139303482587

now we have:
58 is 0.72139303482587% of 8040
