62.8 is what percent of 721 - 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 721 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 721, so we can write it down as 100%=721.
4. We know, that x% equals 62.8 of the output value, so we can write it down as x%=62.8.
5. Now we have two simple equations:
1) 100%=721
2) x%=62.8
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%=721/62.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 62.8 is what percent of 721

100%/x%=721/62.8
(100/x)*x=(721/62.8)*x       - we multiply both sides of the equation by x
100=11.480891719745*x       - we divide both sides of the equation by (11.480891719745) to get x
100/11.480891719745=x
8.7101248266297=x
x=8.7101248266297

now we have:
62.8 is 8.7101248266297% of 721
