53.9 is what percent of 650 - 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 650 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 650, so we can write it down as 100%=650.
4. We know, that x% equals 53.9 of the output value, so we can write it down as x%=53.9.
5. Now we have two simple equations:
1) 100%=650
2) x%=53.9
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%=650/53.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53.9 is what percent of 650

100%/x%=650/53.9
(100/x)*x=(650/53.9)*x       - we multiply both sides of the equation by x
100=12.059369202226*x       - we divide both sides of the equation by (12.059369202226) to get x
100/12.059369202226=x
8.2923076923077=x
x=8.2923076923077

now we have:
53.9 is 8.2923076923077% of 650
