What is 4.49 percent of 21.5 - 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 21.5 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 21.5 is 100%, so we can write it down as 21.5=100%.
4. We know, that x is 4.49% of the output value, so we can write it down as x=4.49%.
5. Now we have two simple equations:
1) 21.5=100%
2) x=4.49%
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:
21.5/x=100%/4.49%
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 4.49% of 21.5

21.5/x=100/4.49
(21.5/x)*x=(100/4.49)*x       - we multiply both sides of the equation by x
21.5=22.271714922049*x       - we divide both sides of the equation by (22.271714922049) to get x
21.5/22.271714922049=x
0.96535=x
x=0.96535

now we have:
4.49% of 21.5=0.96535
