216.5 is what percent of 1802.5 - 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 1802.5 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 1802.5, so we can write it down as 100%=1802.5.
4. We know, that x% equals 216.5 of the output value, so we can write it down as x%=216.5.
5. Now we have two simple equations:
1) 100%=1802.5
2) x%=216.5
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%=1802.5/216.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 216.5 is what percent of 1802.5

100%/x%=1802.5/216.5
(100/x)*x=(1802.5/216.5)*x       - we multiply both sides of the equation by x
100=8.3256351039261*x       - we divide both sides of the equation by (8.3256351039261) to get x
100/8.3256351039261=x
12.011095700416=x
x=12.011095700416

now we have:
216.5 is 12.011095700416% of 1802.5
