198.6 is what percent of 1655 - 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 1655 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 1655, so we can write it down as 100%=1655.
4. We know, that x% equals 198.6 of the output value, so we can write it down as x%=198.6.
5. Now we have two simple equations:
1) 100%=1655
2) x%=198.6
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%=1655/198.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 198.6 is what percent of 1655

100%/x%=1655/198.6
(100/x)*x=(1655/198.6)*x       - we multiply both sides of the equation by x
100=8.3333333333333*x       - we divide both sides of the equation by (8.3333333333333) to get x
100/8.3333333333333=x
12=x
x=12

now we have:
198.6 is 12% of 1655
