73.39 is what percent of 685 - 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 685 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 685, so we can write it down as 100%=685.
4. We know, that x% equals 73.39 of the output value, so we can write it down as x%=73.39.
5. Now we have two simple equations:
1) 100%=685
2) x%=73.39
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%=685/73.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 73.39 is what percent of 685

100%/x%=685/73.39
(100/x)*x=(685/73.39)*x       - we multiply both sides of the equation by x
100=9.3336966889222*x       - we divide both sides of the equation by (9.3336966889222) to get x
100/9.3336966889222=x
10.713868613139=x
x=10.713868613139

now we have:
73.39 is 10.713868613139% of 685
