2.17 is what percent of 0.99 - 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 0.99 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 0.99, so we can write it down as 100%=0.99.
4. We know, that x% equals 2.17 of the output value, so we can write it down as x%=2.17.
5. Now we have two simple equations:
1) 100%=0.99
2) x%=2.17
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%=0.99/2.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.17 is what percent of 0.99

100%/x%=0.99/2.17
(100/x)*x=(0.99/2.17)*x       - we multiply both sides of the equation by x
100=0.45622119815668*x       - we divide both sides of the equation by (0.45622119815668) to get x
100/0.45622119815668=x
219.19191919192=x
x=219.19191919192

now we have:
2.17 is 219.19191919192% of 0.99
