622.5 is what percent of 972 - 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 972 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 972, so we can write it down as 100%=972.
4. We know, that x% equals 622.5 of the output value, so we can write it down as x%=622.5.
5. Now we have two simple equations:
1) 100%=972
2) x%=622.5
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%=972/622.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 622.5 is what percent of 972

100%/x%=972/622.5
(100/x)*x=(972/622.5)*x       - we multiply both sides of the equation by x
100=1.5614457831325*x       - we divide both sides of the equation by (1.5614457831325) to get x
100/1.5614457831325=x
64.043209876543=x
x=64.043209876543

now we have:
622.5 is 64.043209876543% of 972
