216.25 is what percent of 270 - 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 270 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 270, so we can write it down as 100%=270.
4. We know, that x% equals 216.25 of the output value, so we can write it down as x%=216.25.
5. Now we have two simple equations:
1) 100%=270
2) x%=216.25
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%=270/216.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 216.25 is what percent of 270

100%/x%=270/216.25
(100/x)*x=(270/216.25)*x       - we multiply both sides of the equation by x
100=1.2485549132948*x       - we divide both sides of the equation by (1.2485549132948) to get x
100/1.2485549132948=x
80.092592592593=x
x=80.092592592593

now we have:
216.25 is 80.092592592593% of 270
