372.3 is what percent of 510 - 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 510 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 510, so we can write it down as 100%=510.
4. We know, that x% equals 372.3 of the output value, so we can write it down as x%=372.3.
5. Now we have two simple equations:
1) 100%=510
2) x%=372.3
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%=510/372.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 372.3 is what percent of 510

100%/x%=510/372.3
(100/x)*x=(510/372.3)*x       - we multiply both sides of the equation by x
100=1.3698630136986*x       - we divide both sides of the equation by (1.3698630136986) to get x
100/1.3698630136986=x
73=x
x=73

now we have:
372.3 is 73% of 510
