19 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 19 of the output value, so we can write it down as x%=19.
5. Now we have two simple equations:
1) 100%=432
2) x%=19
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%=432/19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19 is what percent of 432

100%/x%=432/19
(100/x)*x=(432/19)*x       - we multiply both sides of the equation by x
100=22.736842105263*x       - we divide both sides of the equation by (22.736842105263) to get x
100/22.736842105263=x
4.3981481481481=x
x=4.3981481481481

now we have:
19 is 4.3981481481481% of 432
