15.75 is what percent of 504 - 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 504 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 504, so we can write it down as 100%=504.
4. We know, that x% equals 15.75 of the output value, so we can write it down as x%=15.75.
5. Now we have two simple equations:
1) 100%=504
2) x%=15.75
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%=504/15.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.75 is what percent of 504

100%/x%=504/15.75
(100/x)*x=(504/15.75)*x       - we multiply both sides of the equation by x
100=32*x       - we divide both sides of the equation by (32) to get x
100/32=x
3.125=x
x=3.125

now we have:
15.75 is 3.125% of 504
