217.52 is what percent of 1320 - 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 1320 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 1320, so we can write it down as 100%=1320.
4. We know, that x% equals 217.52 of the output value, so we can write it down as x%=217.52.
5. Now we have two simple equations:
1) 100%=1320
2) x%=217.52
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%=1320/217.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 217.52 is what percent of 1320

100%/x%=1320/217.52
(100/x)*x=(1320/217.52)*x       - we multiply both sides of the equation by x
100=6.0684075027584*x       - we divide both sides of the equation by (6.0684075027584) to get x
100/6.0684075027584=x
16.478787878788=x
x=16.478787878788

now we have:
217.52 is 16.478787878788% of 1320
