What is 42 percent of 33.18 - 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 33.18 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 33.18 is 100%, so we can write it down as 33.18=100%.
4. We know, that x is 42% of the output value, so we can write it down as x=42%.
5. Now we have two simple equations:
1) 33.18=100%
2) x=42%
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:
33.18/x=100%/42%
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 42% of 33.18

33.18/x=100/42
(33.18/x)*x=(100/42)*x       - we multiply both sides of the equation by x
33.18=2.3809523809524*x       - we divide both sides of the equation by (2.3809523809524) to get x
33.18/2.3809523809524=x
13.9356=x
x=13.9356

now we have:
42% of 33.18=13.9356
