5.5 is what percent of 7.15 - 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 7.15 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 7.15, so we can write it down as 100%=7.15.
4. We know, that x% equals 5.5 of the output value, so we can write it down as x%=5.5.
5. Now we have two simple equations:
1) 100%=7.15
2) x%=5.5
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%=7.15/5.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.5 is what percent of 7.15

100%/x%=7.15/5.5
(100/x)*x=(7.15/5.5)*x       - we multiply both sides of the equation by x
100=1.3*x       - we divide both sides of the equation by (1.3) to get x
100/1.3=x
76.923076923077=x
x=76.923076923077

now we have:
5.5 is 76.923076923077% of 7.15
