What is 9.2 percent of 42400 - 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 42400 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 42400 is 100%, so we can write it down as 42400=100%.
4. We know, that x is 9.2% of the output value, so we can write it down as x=9.2%.
5. Now we have two simple equations:
1) 42400=100%
2) x=9.2%
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:
42400/x=100%/9.2%
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 9.2% of 42400

42400/x=100/9.2
(42400/x)*x=(100/9.2)*x       - we multiply both sides of the equation by x
42400=10.869565217391*x       - we divide both sides of the equation by (10.869565217391) to get x
42400/10.869565217391=x
3900.8=x
x=3900.8

now we have:
9.2% of 42400=3900.8
