What is 23 percent of 9.9 - 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 9.9 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 9.9 is 100%, so we can write it down as 9.9=100%.
4. We know, that x is 23% of the output value, so we can write it down as x=23%.
5. Now we have two simple equations:
1) 9.9=100%
2) x=23%
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:
9.9/x=100%/23%
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 23% of 9.9

9.9/x=100/23
(9.9/x)*x=(100/23)*x       - we multiply both sides of the equation by x
9.9=4.3478260869565*x       - we divide both sides of the equation by (4.3478260869565) to get x
9.9/4.3478260869565=x
2.277=x
x=2.277

now we have:
23% of 9.9=2.277
