What is 23.97 percent of 78.21 - 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 78.21 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 78.21 is 100%, so we can write it down as 78.21=100%.
4. We know, that x is 23.97% of the output value, so we can write it down as x=23.97%.
5. Now we have two simple equations:
1) 78.21=100%
2) x=23.97%
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:
78.21/x=100%/23.97%
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 23.97% of 78.21

78.21/x=100/23.97
(78.21/x)*x=(100/23.97)*x       - we multiply both sides of the equation by x
78.21=4.1718815185649*x       - we divide both sides of the equation by (4.1718815185649) to get x
78.21/4.1718815185649=x
18.746937=x
x=18.746937

now we have:
23.97% of 78.21=18.746937
