197.5 is what percent of 790 - 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 790 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 790, so we can write it down as 100%=790.
4. We know, that x% equals 197.5 of the output value, so we can write it down as x%=197.5.
5. Now we have two simple equations:
1) 100%=790
2) x%=197.5
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%=790/197.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 197.5 is what percent of 790

100%/x%=790/197.5
(100/x)*x=(790/197.5)*x       - we multiply both sides of the equation by x
100=4*x       - we divide both sides of the equation by (4) to get x
100/4=x
25=x
x=25

now we have:
197.5 is 25% of 790
