620.2 is what percent of 712 - 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 712 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 712, so we can write it down as 100%=712.
4. We know, that x% equals 620.2 of the output value, so we can write it down as x%=620.2.
5. Now we have two simple equations:
1) 100%=712
2) x%=620.2
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%=712/620.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 620.2 is what percent of 712

100%/x%=712/620.2
(100/x)*x=(712/620.2)*x       - we multiply both sides of the equation by x
100=1.1480167687843*x       - we divide both sides of the equation by (1.1480167687843) to get x
100/1.1480167687843=x
87.106741573034=x
x=87.106741573034

now we have:
620.2 is 87.106741573034% of 712
