6.15 is what percent of 216 - 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 216 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 216, so we can write it down as 100%=216.
4. We know, that x% equals 6.15 of the output value, so we can write it down as x%=6.15.
5. Now we have two simple equations:
1) 100%=216
2) x%=6.15
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%=216/6.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.15 is what percent of 216

100%/x%=216/6.15
(100/x)*x=(216/6.15)*x       - we multiply both sides of the equation by x
100=35.121951219512*x       - we divide both sides of the equation by (35.121951219512) to get x
100/35.121951219512=x
2.8472222222222=x
x=2.8472222222222

now we have:
6.15 is 2.8472222222222% of 216
