What is 1980 percent of 1100 - 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 1100 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 1100 is 100%, so we can write it down as 1100=100%.
4. We know, that x is 1980% of the output value, so we can write it down as x=1980%.
5. Now we have two simple equations:
1) 1100=100%
2) x=1980%
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:
1100/x=100%/1980%
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 1980% of 1100

1100/x=100/1980
(1100/x)*x=(100/1980)*x       - we multiply both sides of the equation by x
1100=0.050505050505051*x       - we divide both sides of the equation by (0.050505050505051) to get x
1100/0.050505050505051=x
21780=x
x=21780

now we have:
1980% of 1100=21780
