What is 9.6 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 9.6% of the output value, so we can write it down as x=9.6%.
5. Now we have two simple equations:
1) 42=100%
2) x=9.6%
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%/9.6%
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 9.6% of 42

42/x=100/9.6
(42/x)*x=(100/9.6)*x       - we multiply both sides of the equation by x
42=10.416666666667*x       - we divide both sides of the equation by (10.416666666667) to get x
42/10.416666666667=x
4.032=x
x=4.032

now we have:
9.6% of 42=4.032
