88.4 is what percent of 3930 - 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 3930 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 3930, so we can write it down as 100%=3930.
4. We know, that x% equals 88.4 of the output value, so we can write it down as x%=88.4.
5. Now we have two simple equations:
1) 100%=3930
2) x%=88.4
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%=3930/88.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 88.4 is what percent of 3930

100%/x%=3930/88.4
(100/x)*x=(3930/88.4)*x       - we multiply both sides of the equation by x
100=44.457013574661*x       - we divide both sides of the equation by (44.457013574661) to get x
100/44.457013574661=x
2.2493638676845=x
x=2.2493638676845

now we have:
88.4 is 2.2493638676845% of 3930
