66 is what percent of 497 - 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 497 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 497, so we can write it down as 100%=497.
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%=497
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%=497/66
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 497

100%/x%=497/66
(100/x)*x=(497/66)*x       - we multiply both sides of the equation by x
100=7.530303030303*x       - we divide both sides of the equation by (7.530303030303) to get x
100/7.530303030303=x
13.27967806841=x
x=13.27967806841

now we have:
66 is 13.27967806841% of 497
