12.25 is what percent of 20.99 - 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 20.99 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 20.99, so we can write it down as 100%=20.99.
4. We know, that x% equals 12.25 of the output value, so we can write it down as x%=12.25.
5. Now we have two simple equations:
1) 100%=20.99
2) x%=12.25
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%=20.99/12.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.25 is what percent of 20.99

100%/x%=20.99/12.25
(100/x)*x=(20.99/12.25)*x       - we multiply both sides of the equation by x
100=1.7134693877551*x       - we divide both sides of the equation by (1.7134693877551) to get x
100/1.7134693877551=x
58.361124344926=x
x=58.361124344926

now we have:
12.25 is 58.361124344926% of 20.99
