9.89 is what percent of 655 - 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 655 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 655, so we can write it down as 100%=655.
4. We know, that x% equals 9.89 of the output value, so we can write it down as x%=9.89.
5. Now we have two simple equations:
1) 100%=655
2) x%=9.89
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%=655/9.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.89 is what percent of 655

100%/x%=655/9.89
(100/x)*x=(655/9.89)*x       - we multiply both sides of the equation by x
100=66.228513650152*x       - we divide both sides of the equation by (66.228513650152) to get x
100/66.228513650152=x
1.5099236641221=x
x=1.5099236641221

now we have:
9.89 is 1.5099236641221% of 655
