19.8 is what percent of 324 - 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 324 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 324, so we can write it down as 100%=324.
4. We know, that x% equals 19.8 of the output value, so we can write it down as x%=19.8.
5. Now we have two simple equations:
1) 100%=324
2) x%=19.8
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%=324/19.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.8 is what percent of 324

100%/x%=324/19.8
(100/x)*x=(324/19.8)*x       - we multiply both sides of the equation by x
100=16.363636363636*x       - we divide both sides of the equation by (16.363636363636) to get x
100/16.363636363636=x
6.1111111111111=x
x=6.1111111111111

now we have:
19.8 is 6.1111111111111% of 324
