158.5 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 158.5 of the output value, so we can write it down as x%=158.5.
5. Now we have two simple equations:
1) 100%=197
2) x%=158.5
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%=197/158.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 158.5 is what percent of 197

100%/x%=197/158.5
(100/x)*x=(197/158.5)*x       - we multiply both sides of the equation by x
100=1.2429022082019*x       - we divide both sides of the equation by (1.2429022082019) to get x
100/1.2429022082019=x
80.456852791878=x
x=80.456852791878

now we have:
158.5 is 80.456852791878% of 197
