73.6 is what percent of 138 - 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 138 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 138, so we can write it down as 100%=138.
4. We know, that x% equals 73.6 of the output value, so we can write it down as x%=73.6.
5. Now we have two simple equations:
1) 100%=138
2) x%=73.6
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%=138/73.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73.6 is what percent of 138

100%/x%=138/73.6
(100/x)*x=(138/73.6)*x       - we multiply both sides of the equation by x
100=1.875*x       - we divide both sides of the equation by (1.875) to get x
100/1.875=x
53.333333333333=x
x=53.333333333333

now we have:
73.6 is 53.333333333333% of 138
