197.2 is what percent of 200.5 - 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 200.5 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 200.5, so we can write it down as 100%=200.5.
4. We know, that x% equals 197.2 of the output value, so we can write it down as x%=197.2.
5. Now we have two simple equations:
1) 100%=200.5
2) x%=197.2
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%=200.5/197.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 197.2 is what percent of 200.5

100%/x%=200.5/197.2
(100/x)*x=(200.5/197.2)*x       - we multiply both sides of the equation by x
100=1.0167342799189*x       - we divide both sides of the equation by (1.0167342799189) to get x
100/1.0167342799189=x
98.354114713217=x
x=98.354114713217

now we have:
197.2 is 98.354114713217% of 200.5
