What is 1120 percent of 840 - 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 840 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 840 is 100%, so we can write it down as 840=100%.
4. We know, that x is 1120% of the output value, so we can write it down as x=1120%.
5. Now we have two simple equations:
1) 840=100%
2) x=1120%
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:
840/x=100%/1120%
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 1120% of 840

840/x=100/1120
(840/x)*x=(100/1120)*x       - we multiply both sides of the equation by x
840=0.089285714285714*x       - we divide both sides of the equation by (0.089285714285714) to get x
840/0.089285714285714=x
9408=x
x=9408

now we have:
1120% of 840=9408
