202.8 is what percent of 845 - 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 845 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 845, so we can write it down as 100%=845.
4. We know, that x% equals 202.8 of the output value, so we can write it down as x%=202.8.
5. Now we have two simple equations:
1) 100%=845
2) x%=202.8
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%=845/202.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 202.8 is what percent of 845

100%/x%=845/202.8
(100/x)*x=(845/202.8)*x       - we multiply both sides of the equation by x
100=4.1666666666667*x       - we divide both sides of the equation by (4.1666666666667) to get x
100/4.1666666666667=x
24=x
x=24

now we have:
202.8 is 24% of 845
