0.2 is what percent of 7.94 - 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 7.94 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 7.94, so we can write it down as 100%=7.94.
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%=7.94
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%=7.94/0.2
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 7.94

100%/x%=7.94/0.2
(100/x)*x=(7.94/0.2)*x       - we multiply both sides of the equation by x
100=39.7*x       - we divide both sides of the equation by (39.7) to get x
100/39.7=x
2.5188916876574=x
x=2.5188916876574

now we have:
0.2 is 2.5188916876574% of 7.94
