66.47 is what percent of 749 - 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 749 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 749, so we can write it down as 100%=749.
4. We know, that x% equals 66.47 of the output value, so we can write it down as x%=66.47.
5. Now we have two simple equations:
1) 100%=749
2) x%=66.47
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%=749/66.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.47 is what percent of 749

100%/x%=749/66.47
(100/x)*x=(749/66.47)*x       - we multiply both sides of the equation by x
100=11.26824131187*x       - we divide both sides of the equation by (11.26824131187) to get x
100/11.26824131187=x
8.8744993324433=x
x=8.8744993324433

now we have:
66.47 is 8.8744993324433% of 749
