What is 2.75 percent of 15.21 - 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 15.21 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 15.21 is 100%, so we can write it down as 15.21=100%.
4. We know, that x is 2.75% of the output value, so we can write it down as x=2.75%.
5. Now we have two simple equations:
1) 15.21=100%
2) x=2.75%
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:
15.21/x=100%/2.75%
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 2.75% of 15.21

15.21/x=100/2.75
(15.21/x)*x=(100/2.75)*x       - we multiply both sides of the equation by x
15.21=36.363636363636*x       - we divide both sides of the equation by (36.363636363636) to get x
15.21/36.363636363636=x
0.418275=x
x=0.418275

now we have:
2.75% of 15.21=0.418275
