0.66 is what percent of 0.73 - 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 0.73 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 0.73, so we can write it down as 100%=0.73.
4. We know, that x% equals 0.66 of the output value, so we can write it down as x%=0.66.
5. Now we have two simple equations:
1) 100%=0.73
2) x%=0.66
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%=0.73/0.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.66 is what percent of 0.73

100%/x%=0.73/0.66
(100/x)*x=(0.73/0.66)*x       - we multiply both sides of the equation by x
100=1.1060606060606*x       - we divide both sides of the equation by (1.1060606060606) to get x
100/1.1060606060606=x
90.41095890411=x
x=90.41095890411

now we have:
0.66 is 90.41095890411% of 0.73
