38 is what percent of 432 - 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 432 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 432, so we can write it down as 100%=432.
4. We know, that x% equals 38 of the output value, so we can write it down as x%=38.
5. Now we have two simple equations:
1) 100%=432
2) x%=38
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%=432/38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38 is what percent of 432

100%/x%=432/38
(100/x)*x=(432/38)*x       - we multiply both sides of the equation by x
100=11.368421052632*x       - we divide both sides of the equation by (11.368421052632) to get x
100/11.368421052632=x
8.7962962962963=x
x=8.7962962962963

now we have:
38 is 8.7962962962963% of 432
