12.5 is what percent of 282 - 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 282 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 282, so we can write it down as 100%=282.
4. We know, that x% equals 12.5 of the output value, so we can write it down as x%=12.5.
5. Now we have two simple equations:
1) 100%=282
2) x%=12.5
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%=282/12.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.5 is what percent of 282

100%/x%=282/12.5
(100/x)*x=(282/12.5)*x       - we multiply both sides of the equation by x
100=22.56*x       - we divide both sides of the equation by (22.56) to get x
100/22.56=x
4.4326241134752=x
x=4.4326241134752

now we have:
12.5 is 4.4326241134752% of 282
