What is 30.4 percent of 27 - 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 27 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 27 is 100%, so we can write it down as 27=100%.
4. We know, that x is 30.4% of the output value, so we can write it down as x=30.4%.
5. Now we have two simple equations:
1) 27=100%
2) x=30.4%
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:
27/x=100%/30.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 30.4% of 27

27/x=100/30.4
(27/x)*x=(100/30.4)*x       - we multiply both sides of the equation by x
27=3.2894736842105*x       - we divide both sides of the equation by (3.2894736842105) to get x
27/3.2894736842105=x
8.208=x
x=8.208

now we have:
30.4% of 27=8.208
