52 is what percent of 68.9 - 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 68.9 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 68.9, so we can write it down as 100%=68.9.
4. We know, that x% equals 52 of the output value, so we can write it down as x%=52.
5. Now we have two simple equations:
1) 100%=68.9
2) x%=52
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%=68.9/52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52 is what percent of 68.9

100%/x%=68.9/52
(100/x)*x=(68.9/52)*x       - we multiply both sides of the equation by x
100=1.325*x       - we divide both sides of the equation by (1.325) to get x
100/1.325=x
75.471698113208=x
x=75.471698113208

now we have:
52 is 75.471698113208% of 68.9
