What is 28.9 percent of 36 - 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 36 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 36 is 100%, so we can write it down as 36=100%.
4. We know, that x is 28.9% of the output value, so we can write it down as x=28.9%.
5. Now we have two simple equations:
1) 36=100%
2) x=28.9%
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:
36/x=100%/28.9%
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 28.9% of 36

36/x=100/28.9
(36/x)*x=(100/28.9)*x       - we multiply both sides of the equation by x
36=3.4602076124567*x       - we divide both sides of the equation by (3.4602076124567) to get x
36/3.4602076124567=x
10.404=x
x=10.404

now we have:
28.9% of 36=10.404
