7.83 is what percent of 66 - 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 66 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 66, so we can write it down as 100%=66.
4. We know, that x% equals 7.83 of the output value, so we can write it down as x%=7.83.
5. Now we have two simple equations:
1) 100%=66
2) x%=7.83
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%=66/7.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.83 is what percent of 66

100%/x%=66/7.83
(100/x)*x=(66/7.83)*x       - we multiply both sides of the equation by x
100=8.4291187739464*x       - we divide both sides of the equation by (8.4291187739464) to get x
100/8.4291187739464=x
11.863636363636=x
x=11.863636363636

now we have:
7.83 is 11.863636363636% of 66
