What is 28.5 percent of 286 - 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 286 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 286 is 100%, so we can write it down as 286=100%.
4. We know, that x is 28.5% of the output value, so we can write it down as x=28.5%.
5. Now we have two simple equations:
1) 286=100%
2) x=28.5%
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:
286/x=100%/28.5%
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 28.5% of 286

286/x=100/28.5
(286/x)*x=(100/28.5)*x       - we multiply both sides of the equation by x
286=3.5087719298246*x       - we divide both sides of the equation by (3.5087719298246) to get x
286/3.5087719298246=x
81.51=x
x=81.51

now we have:
28.5% of 286=81.51
