66.75 is what percent of 156 - 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 156 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 156, so we can write it down as 100%=156.
4. We know, that x% equals 66.75 of the output value, so we can write it down as x%=66.75.
5. Now we have two simple equations:
1) 100%=156
2) x%=66.75
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%=156/66.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.75 is what percent of 156

100%/x%=156/66.75
(100/x)*x=(156/66.75)*x       - we multiply both sides of the equation by x
100=2.3370786516854*x       - we divide both sides of the equation by (2.3370786516854) to get x
100/2.3370786516854=x
42.788461538462=x
x=42.788461538462

now we have:
66.75 is 42.788461538462% of 156
