399 is what percent of 1832 - 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 1832 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 1832, so we can write it down as 100%=1832.
4. We know, that x% equals 399 of the output value, so we can write it down as x%=399.
5. Now we have two simple equations:
1) 100%=1832
2) x%=399
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%=1832/399
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 399 is what percent of 1832

100%/x%=1832/399
(100/x)*x=(1832/399)*x       - we multiply both sides of the equation by x
100=4.5914786967419*x       - we divide both sides of the equation by (4.5914786967419) to get x
100/4.5914786967419=x
21.779475982533=x
x=21.779475982533

now we have:
399 is 21.779475982533% of 1832
