What is 76.19 percent of 20 - 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 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 is 100%, so we can write it down as 20=100%.
4. We know, that x is 76.19% of the output value, so we can write it down as x=76.19%.
5. Now we have two simple equations:
1) 20=100%
2) x=76.19%
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/x=100%/76.19%
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 76.19% of 20

20/x=100/76.19
(20/x)*x=(100/76.19)*x       - we multiply both sides of the equation by x
20=1.3125082031763*x       - we divide both sides of the equation by (1.3125082031763) to get x
20/1.3125082031763=x
15.238=x
x=15.238

now we have:
76.19% of 20=15.238
