723.6 is what percent of 402 - 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 402 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 402, so we can write it down as 100%=402.
4. We know, that x% equals 723.6 of the output value, so we can write it down as x%=723.6.
5. Now we have two simple equations:
1) 100%=402
2) x%=723.6
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%=402/723.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 723.6 is what percent of 402

100%/x%=402/723.6
(100/x)*x=(402/723.6)*x       - we multiply both sides of the equation by x
100=0.55555555555556*x       - we divide both sides of the equation by (0.55555555555556) to get x
100/0.55555555555556=x
180=x
x=180

now we have:
723.6 is 180% of 402
