63.75 is what percent of 280 - 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 280 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 280, so we can write it down as 100%=280.
4. We know, that x% equals 63.75 of the output value, so we can write it down as x%=63.75.
5. Now we have two simple equations:
1) 100%=280
2) x%=63.75
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%=280/63.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 63.75 is what percent of 280

100%/x%=280/63.75
(100/x)*x=(280/63.75)*x       - we multiply both sides of the equation by x
100=4.3921568627451*x       - we divide both sides of the equation by (4.3921568627451) to get x
100/4.3921568627451=x
22.767857142857=x
x=22.767857142857

now we have:
63.75 is 22.767857142857% of 280
