What is 21.12 percent of 98 - 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 98 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 98 is 100%, so we can write it down as 98=100%.
4. We know, that x is 21.12% of the output value, so we can write it down as x=21.12%.
5. Now we have two simple equations:
1) 98=100%
2) x=21.12%
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:
98/x=100%/21.12%
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 21.12% of 98

98/x=100/21.12
(98/x)*x=(100/21.12)*x       - we multiply both sides of the equation by x
98=4.7348484848485*x       - we divide both sides of the equation by (4.7348484848485) to get x
98/4.7348484848485=x
20.6976=x
x=20.6976

now we have:
21.12% of 98=20.6976
