66 is what percent of 673 - 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 673 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 673, so we can write it down as 100%=673.
4. We know, that x% equals 66 of the output value, so we can write it down as x%=66.
5. Now we have two simple equations:
1) 100%=673
2) x%=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%=673/66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66 is what percent of 673

100%/x%=673/66
(100/x)*x=(673/66)*x       - we multiply both sides of the equation by x
100=10.19696969697*x       - we divide both sides of the equation by (10.19696969697) to get x
100/10.19696969697=x
9.8068350668648=x
x=9.8068350668648

now we have:
66 is 9.8068350668648% of 673
