What is 115 percent of 1240 - 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 1240 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 1240 is 100%, so we can write it down as 1240=100%.
4. We know, that x is 115% of the output value, so we can write it down as x=115%.
5. Now we have two simple equations:
1) 1240=100%
2) x=115%
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:
1240/x=100%/115%
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 115% of 1240

1240/x=100/115
(1240/x)*x=(100/115)*x       - we multiply both sides of the equation by x
1240=0.869565217391*x       - we divide both sides of the equation by (0.869565217391) to get x
1240/0.869565217391=x
1426=x
x=1426

now we have:
115% of 1240=1426
