4.36 is what percent of 399 - 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 399 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 399, so we can write it down as 100%=399.
4. We know, that x% equals 4.36 of the output value, so we can write it down as x%=4.36.
5. Now we have two simple equations:
1) 100%=399
2) x%=4.36
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%=399/4.36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.36 is what percent of 399

100%/x%=399/4.36
(100/x)*x=(399/4.36)*x       - we multiply both sides of the equation by x
100=91.51376146789*x       - we divide both sides of the equation by (91.51376146789) to get x
100/91.51376146789=x
1.0927318295739=x
x=1.0927318295739

now we have:
4.36 is 1.0927318295739% of 399
