577.29 is what percent of 742.5 - 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 742.5 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 742.5, so we can write it down as 100%=742.5.
4. We know, that x% equals 577.29 of the output value, so we can write it down as x%=577.29.
5. Now we have two simple equations:
1) 100%=742.5
2) x%=577.29
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%=742.5/577.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 577.29 is what percent of 742.5

100%/x%=742.5/577.29
(100/x)*x=(742.5/577.29)*x       - we multiply both sides of the equation by x
100=1.2861819882555*x       - we divide both sides of the equation by (1.2861819882555) to get x
100/1.2861819882555=x
77.749494949495=x
x=77.749494949495

now we have:
577.29 is 77.749494949495% of 742.5
