81.42 is what percent of 59 - 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 59 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 59, so we can write it down as 100%=59.
4. We know, that x% equals 81.42 of the output value, so we can write it down as x%=81.42.
5. Now we have two simple equations:
1) 100%=59
2) x%=81.42
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%=59/81.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.42 is what percent of 59

100%/x%=59/81.42
(100/x)*x=(59/81.42)*x       - we multiply both sides of the equation by x
100=0.72463768115942*x       - we divide both sides of the equation by (0.72463768115942) to get x
100/0.72463768115942=x
138=x
x=138

now we have:
81.42 is 138% of 59
