74.74 is what percent of 393 - 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 393 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 393, so we can write it down as 100%=393.
4. We know, that x% equals 74.74 of the output value, so we can write it down as x%=74.74.
5. Now we have two simple equations:
1) 100%=393
2) x%=74.74
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%=393/74.74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.74 is what percent of 393

100%/x%=393/74.74
(100/x)*x=(393/74.74)*x       - we multiply both sides of the equation by x
100=5.2582285255553*x       - we divide both sides of the equation by (5.2582285255553) to get x
100/5.2582285255553=x
19.017811704835=x
x=19.017811704835

now we have:
74.74 is 19.017811704835% of 393
