0.2 is what percent of 197 - 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 197 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 197, so we can write it down as 100%=197.
4. We know, that x% equals 0.2 of the output value, so we can write it down as x%=0.2.
5. Now we have two simple equations:
1) 100%=197
2) x%=0.2
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%=197/0.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.2 is what percent of 197

100%/x%=197/0.2
(100/x)*x=(197/0.2)*x       - we multiply both sides of the equation by x
100=985*x       - we divide both sides of the equation by (985) to get x
100/985=x
0.10152284263959=x
x=0.10152284263959

now we have:
0.2 is 0.10152284263959% of 197
