49.9 is what percent of 66 - 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 66 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 66, so we can write it down as 100%=66.
4. We know, that x% equals 49.9 of the output value, so we can write it down as x%=49.9.
5. Now we have two simple equations:
1) 100%=66
2) x%=49.9
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%=66/49.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49.9 is what percent of 66

100%/x%=66/49.9
(100/x)*x=(66/49.9)*x       - we multiply both sides of the equation by x
100=1.3226452905812*x       - we divide both sides of the equation by (1.3226452905812) to get x
100/1.3226452905812=x
75.606060606061=x
x=75.606060606061

now we have:
49.9 is 75.606060606061% of 66
