7.18 is what percent of 86.99 - 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 86.99 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 86.99, so we can write it down as 100%=86.99.
4. We know, that x% equals 7.18 of the output value, so we can write it down as x%=7.18.
5. Now we have two simple equations:
1) 100%=86.99
2) x%=7.18
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%=86.99/7.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.18 is what percent of 86.99

100%/x%=86.99/7.18
(100/x)*x=(86.99/7.18)*x       - we multiply both sides of the equation by x
100=12.115598885794*x       - we divide both sides of the equation by (12.115598885794) to get x
100/12.115598885794=x
8.2538222784228=x
x=8.2538222784228

now we have:
7.18 is 8.2538222784228% of 86.99
