287.5 is what percent of 23 - 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 23 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 23, so we can write it down as 100%=23.
4. We know, that x% equals 287.5 of the output value, so we can write it down as x%=287.5.
5. Now we have two simple equations:
1) 100%=23
2) x%=287.5
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%=23/287.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 287.5 is what percent of 23

100%/x%=23/287.5
(100/x)*x=(23/287.5)*x       - we multiply both sides of the equation by x
100=0.08*x       - we divide both sides of the equation by (0.08) to get x
100/0.08=x
1250=x
x=1250

now we have:
287.5 is 1250% of 23
