717.54 is what percent of 900 - 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 900 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 900, so we can write it down as 100%=900.
4. We know, that x% equals 717.54 of the output value, so we can write it down as x%=717.54.
5. Now we have two simple equations:
1) 100%=900
2) x%=717.54
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%=900/717.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 717.54 is what percent of 900

100%/x%=900/717.54
(100/x)*x=(900/717.54)*x       - we multiply both sides of the equation by x
100=1.2542854753742*x       - we divide both sides of the equation by (1.2542854753742) to get x
100/1.2542854753742=x
79.726666666667=x
x=79.726666666667

now we have:
717.54 is 79.726666666667% of 900
