381.3 is what percent of 525 - 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 525 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 525, so we can write it down as 100%=525.
4. We know, that x% equals 381.3 of the output value, so we can write it down as x%=381.3.
5. Now we have two simple equations:
1) 100%=525
2) x%=381.3
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%=525/381.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 381.3 is what percent of 525

100%/x%=525/381.3
(100/x)*x=(525/381.3)*x       - we multiply both sides of the equation by x
100=1.3768686073958*x       - we divide both sides of the equation by (1.3768686073958) to get x
100/1.3768686073958=x
72.628571428571=x
x=72.628571428571

now we have:
381.3 is 72.628571428571% of 525
