388.3 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 388.3 of the output value, so we can write it down as x%=388.3.
5. Now we have two simple equations:
1) 100%=525
2) x%=388.3
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%=525/388.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 388.3 is what percent of 525

100%/x%=525/388.3
(100/x)*x=(525/388.3)*x       - we multiply both sides of the equation by x
100=1.3520473860417*x       - we divide both sides of the equation by (1.3520473860417) to get x
100/1.3520473860417=x
73.961904761905=x
x=73.961904761905

now we have:
388.3 is 73.961904761905% of 525
