667.08 is what percent of 999 - 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 999 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 999, so we can write it down as 100%=999.
4. We know, that x% equals 667.08 of the output value, so we can write it down as x%=667.08.
5. Now we have two simple equations:
1) 100%=999
2) x%=667.08
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%=999/667.08
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 667.08 is what percent of 999

100%/x%=999/667.08
(100/x)*x=(999/667.08)*x       - we multiply both sides of the equation by x
100=1.49757150567*x       - we divide both sides of the equation by (1.49757150567) to get x
100/1.49757150567=x
66.7747747748=x
x=66.7747747748

now we have:
667.08 is 66.7747747748% of 999
