60 is what percent of 647 - 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 647 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 647, so we can write it down as 100%=647.
4. We know, that x% equals 60 of the output value, so we can write it down as x%=60.
5. Now we have two simple equations:
1) 100%=647
2) x%=60
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%=647/60
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 60 is what percent of 647

100%/x%=647/60
(100/x)*x=(647/60)*x       - we multiply both sides of the equation by x
100=10.783333333333*x       - we divide both sides of the equation by (10.783333333333) to get x
100/10.783333333333=x
9.273570324575=x
x=9.273570324575

now we have:
60 is 9.273570324575% of 647
