0.66 is what percent of 7.6 - 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 7.6 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 7.6, so we can write it down as 100%=7.6.
4. We know, that x% equals 0.66 of the output value, so we can write it down as x%=0.66.
5. Now we have two simple equations:
1) 100%=7.6
2) x%=0.66
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%=7.6/0.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.66 is what percent of 7.6

100%/x%=7.6/0.66
(100/x)*x=(7.6/0.66)*x       - we multiply both sides of the equation by x
100=11.515151515152*x       - we divide both sides of the equation by (11.515151515152) to get x
100/11.515151515152=x
8.6842105263158=x
x=8.6842105263158

now we have:
0.66 is 8.6842105263158% of 7.6
