What is 7.15 percent of 42640 - 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 42640 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 42640 is 100%, so we can write it down as 42640=100%.
4. We know, that x is 7.15% of the output value, so we can write it down as x=7.15%.
5. Now we have two simple equations:
1) 42640=100%
2) x=7.15%
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:
42640/x=100%/7.15%
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 7.15% of 42640

42640/x=100/7.15
(42640/x)*x=(100/7.15)*x       - we multiply both sides of the equation by x
42640=13.986013986014*x       - we divide both sides of the equation by (13.986013986014) to get x
42640/13.986013986014=x
3048.76=x
x=3048.76

now we have:
7.15% of 42640=3048.76
