7 is what percent of 79.95 - 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 79.95 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 79.95, so we can write it down as 100%=79.95.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=79.95
2) x%=7
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%=79.95/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 79.95

100%/x%=79.95/7
(100/x)*x=(79.95/7)*x       - we multiply both sides of the equation by x
100=11.421428571429*x       - we divide both sides of the equation by (11.421428571429) to get x
100/11.421428571429=x
8.7554721701063=x
x=8.7554721701063

now we have:
7 is 8.7554721701063% of 79.95
