What is 36 percent of 42.12 - 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 42.12 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 42.12 is 100%, so we can write it down as 42.12=100%.
4. We know, that x is 36% of the output value, so we can write it down as x=36%.
5. Now we have two simple equations:
1) 42.12=100%
2) x=36%
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:
42.12/x=100%/36%
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 36% of 42.12

42.12/x=100/36
(42.12/x)*x=(100/36)*x       - we multiply both sides of the equation by x
42.12=2.7777777777778*x       - we divide both sides of the equation by (2.7777777777778) to get x
42.12/2.7777777777778=x
15.1632=x
x=15.1632

now we have:
36% of 42.12=15.1632
