What is 8.3 percent of 42 - 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 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 is 100%, so we can write it down as 42=100%.
4. We know, that x is 8.3% of the output value, so we can write it down as x=8.3%.
5. Now we have two simple equations:
1) 42=100%
2) x=8.3%
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/x=100%/8.3%
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 8.3% of 42

42/x=100/8.3
(42/x)*x=(100/8.3)*x       - we multiply both sides of the equation by x
42=12.048192771084*x       - we divide both sides of the equation by (12.048192771084) to get x
42/12.048192771084=x
3.486=x
x=3.486

now we have:
8.3% of 42=3.486
