What is 9.4 percent of 20.4 - 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 20.4 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 20.4 is 100%, so we can write it down as 20.4=100%.
4. We know, that x is 9.4% of the output value, so we can write it down as x=9.4%.
5. Now we have two simple equations:
1) 20.4=100%
2) x=9.4%
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:
20.4/x=100%/9.4%
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 9.4% of 20.4

20.4/x=100/9.4
(20.4/x)*x=(100/9.4)*x       - we multiply both sides of the equation by x
20.4=10.63829787234*x       - we divide both sides of the equation by (10.63829787234) to get x
20.4/10.63829787234=x
1.9176=x
x=1.9176

now we have:
9.4% of 20.4=1.9176
