What is 27.75 percent of 42.57 - 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 42.57 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 42.57 is 100%, so we can write it down as 42.57=100%.
4. We know, that x is 27.75% of the output value, so we can write it down as x=27.75%.
5. Now we have two simple equations:
1) 42.57=100%
2) x=27.75%
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:
42.57/x=100%/27.75%
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 27.75% of 42.57

42.57/x=100/27.75
(42.57/x)*x=(100/27.75)*x       - we multiply both sides of the equation by x
42.57=3.6036036036036*x       - we divide both sides of the equation by (3.6036036036036) to get x
42.57/3.6036036036036=x
11.813175=x
x=11.813175

now we have:
27.75% of 42.57=11.813175
