7.68 is what percent of 68 - 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 68 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 68, so we can write it down as 100%=68.
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%=68
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%=68/7.68
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 68

100%/x%=68/7.68
(100/x)*x=(68/7.68)*x       - we multiply both sides of the equation by x
100=8.8541666666667*x       - we divide both sides of the equation by (8.8541666666667) to get x
100/8.8541666666667=x
11.294117647059=x
x=11.294117647059

now we have:
7.68 is 11.294117647059% of 68
