642.6 is what percent of 702 - 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 702 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 702, so we can write it down as 100%=702.
4. We know, that x% equals 642.6 of the output value, so we can write it down as x%=642.6.
5. Now we have two simple equations:
1) 100%=702
2) x%=642.6
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%=702/642.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 642.6 is what percent of 702

100%/x%=702/642.6
(100/x)*x=(702/642.6)*x       - we multiply both sides of the equation by x
100=1.0924369747899*x       - we divide both sides of the equation by (1.0924369747899) to get x
100/1.0924369747899=x
91.538461538462=x
x=91.538461538462

now we have:
642.6 is 91.538461538462% of 702
