What is 640 percent of 1160 - 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 1160 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 1160 is 100%, so we can write it down as 1160=100%.
4. We know, that x is 640% of the output value, so we can write it down as x=640%.
5. Now we have two simple equations:
1) 1160=100%
2) x=640%
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:
1160/x=100%/640%
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 640% of 1160

1160/x=100/640
(1160/x)*x=(100/640)*x       - we multiply both sides of the equation by x
1160=0.15625*x       - we divide both sides of the equation by (0.15625) to get x
1160/0.15625=x
7424=x
x=7424

now we have:
640% of 1160=7424
