0.99 is what percent of 8.15 - 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 8.15 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 8.15, so we can write it down as 100%=8.15.
4. We know, that x% equals 0.99 of the output value, so we can write it down as x%=0.99.
5. Now we have two simple equations:
1) 100%=8.15
2) x%=0.99
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%=8.15/0.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.99 is what percent of 8.15

100%/x%=8.15/0.99
(100/x)*x=(8.15/0.99)*x       - we multiply both sides of the equation by x
100=8.2323232323232*x       - we divide both sides of the equation by (8.2323232323232) to get x
100/8.2323232323232=x
12.147239263804=x
x=12.147239263804

now we have:
0.99 is 12.147239263804% of 8.15
