198.65 is what percent of 678.55 - 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 678.55 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 678.55, so we can write it down as 100%=678.55.
4. We know, that x% equals 198.65 of the output value, so we can write it down as x%=198.65.
5. Now we have two simple equations:
1) 100%=678.55
2) x%=198.65
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%=678.55/198.65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 198.65 is what percent of 678.55

100%/x%=678.55/198.65
(100/x)*x=(678.55/198.65)*x       - we multiply both sides of the equation by x
100=3.4158066951925*x       - we divide both sides of the equation by (3.4158066951925) to get x
100/3.4158066951925=x
29.275661336674=x
x=29.275661336674

now we have:
