What is 109 percent of 1200 - 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 1200 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 1200 is 100%, so we can write it down as 1200=100%.
4. We know, that x is 109% of the output value, so we can write it down as x=109%.
5. Now we have two simple equations:
1) 1200=100%
2) x=109%
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:
1200/x=100%/109%
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 109% of 1200

1200/x=100/109
(1200/x)*x=(100/109)*x       - we multiply both sides of the equation by x
1200=0.91743119266055*x       - we divide both sides of the equation by (0.91743119266055) to get x
1200/0.91743119266055=x
1308=x
x=1308

now we have:
109% of 1200=1308
