8.73 is what percent of 39.7 - 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 39.7 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 39.7, so we can write it down as 100%=39.7.
4. We know, that x% equals 8.73 of the output value, so we can write it down as x%=8.73.
5. Now we have two simple equations:
1) 100%=39.7
2) x%=8.73
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%=39.7/8.73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.73 is what percent of 39.7

100%/x%=39.7/8.73
(100/x)*x=(39.7/8.73)*x       - we multiply both sides of the equation by x
100=4.5475372279496*x       - we divide both sides of the equation by (4.5475372279496) to get x
100/4.5475372279496=x
21.989924433249=x
x=21.989924433249

now we have:
8.73 is 21.989924433249% of 39.7
