What is 2.49 percent of 1540 - 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 1540 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 1540 is 100%, so we can write it down as 1540=100%.
4. We know, that x is 2.49% of the output value, so we can write it down as x=2.49%.
5. Now we have two simple equations:
1) 1540=100%
2) x=2.49%
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:
1540/x=100%/2.49%
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 2.49% of 1540

1540/x=100/2.49
(1540/x)*x=(100/2.49)*x       - we multiply both sides of the equation by x
1540=40.160642570281*x       - we divide both sides of the equation by (40.160642570281) to get x
1540/40.160642570281=x
38.346=x
x=38.346

now we have:
2.49% of 1540=38.346
