What is 57 percent of 13.6 - 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 13.6 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 13.6 is 100%, so we can write it down as 13.6=100%.
4. We know, that x is 57% of the output value, so we can write it down as x=57%.
5. Now we have two simple equations:
1) 13.6=100%
2) x=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:
13.6/x=100%/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 57% of 13.6

13.6/x=100/57
(13.6/x)*x=(100/57)*x       - we multiply both sides of the equation by x
13.6=1.7543859649123*x       - we divide both sides of the equation by (1.7543859649123) to get x
13.6/1.7543859649123=x
7.752=x
x=7.752

now we have:
57% of 13.6=7.752
