What is 63.57 percent of 28 - 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 28 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 28 is 100%, so we can write it down as 28=100%.
4. We know, that x is 63.57% of the output value, so we can write it down as x=63.57%.
5. Now we have two simple equations:
1) 28=100%
2) x=63.57%
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:
28/x=100%/63.57%
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 63.57% of 28

28/x=100/63.57
(28/x)*x=(100/63.57)*x       - we multiply both sides of the equation by x
28=1.5730690577316*x       - we divide both sides of the equation by (1.5730690577316) to get x
28/1.5730690577316=x
17.7996=x
x=17.7996

now we have:
63.57% of 28=17.7996
