612.9 is what percent of 1500 - 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 1500 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 1500, so we can write it down as 100%=1500.
4. We know, that x% equals 612.9 of the output value, so we can write it down as x%=612.9.
5. Now we have two simple equations:
1) 100%=1500
2) x%=612.9
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%=1500/612.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 612.9 is what percent of 1500

100%/x%=1500/612.9
(100/x)*x=(1500/612.9)*x       - we multiply both sides of the equation by x
100=2.4473813020069*x       - we divide both sides of the equation by (2.4473813020069) to get x
100/2.4473813020069=x
40.86=x
x=40.86

now we have:
612.9 is 40.86% of 1500
