716.4 is what percent of 17910 - 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 17910 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 17910, so we can write it down as 100%=17910.
4. We know, that x% equals 716.4 of the output value, so we can write it down as x%=716.4.
5. Now we have two simple equations:
1) 100%=17910
2) x%=716.4
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%=17910/716.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 716.4 is what percent of 17910

100%/x%=17910/716.4
(100/x)*x=(17910/716.4)*x       - we multiply both sides of the equation by x
100=25*x       - we divide both sides of the equation by (25) to get x
100/25=x
4=x
x=4

now we have:
716.4 is 4% of 17910
