3.97 is what percent of 198.05 - 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 198.05 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 198.05, so we can write it down as 100%=198.05.
4. We know, that x% equals 3.97 of the output value, so we can write it down as x%=3.97.
5. Now we have two simple equations:
1) 100%=198.05
2) x%=3.97
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%=198.05/3.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.97 is what percent of 198.05

100%/x%=198.05/3.97
(100/x)*x=(198.05/3.97)*x       - we multiply both sides of the equation by x
100=49.886649874055*x       - we divide both sides of the equation by (49.886649874055) to get x
100/49.886649874055=x
2.0045443069932=x
x=2.0045443069932

now we have:
3.97 is 2.0045443069932% of 198.05
