1 is what percent of 9.91 - 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 9.91 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 9.91, so we can write it down as 100%=9.91.
4. We know, that x% equals 1 of the output value, so we can write it down as x%=1.
5. Now we have two simple equations:
1) 100%=9.91
2) x%=1
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%=9.91/1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1 is what percent of 9.91

100%/x%=9.91/1
(100/x)*x=(9.91/1)*x       - we multiply both sides of the equation by x
100=9.91*x       - we divide both sides of the equation by (9.91) to get x
100/9.91=x
10.090817356206=x
x=10.090817356206

now we have:
1 is 10.090817356206% of 9.91
