7.68 is what percent of 240 - 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 240 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 240, so we can write it down as 100%=240.
4. We know, that x% equals 7.68 of the output value, so we can write it down as x%=7.68.
5. Now we have two simple equations:
1) 100%=240
2) x%=7.68
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%=240/7.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.68 is what percent of 240

100%/x%=240/7.68
(100/x)*x=(240/7.68)*x       - we multiply both sides of the equation by x
100=31.25*x       - we divide both sides of the equation by (31.25) to get x
100/31.25=x
3.2=x
x=3.2

now we have:
7.68 is 3.2% of 240
