Answer:

see below

Explanation:

11 1/5 ÷ 2 3/4

Change to improper fractions

(5*11 +1)/5 ÷ (4*2+3)/4

56/5 ÷ 11/4

Copy dot flip

56/5 * 4/11

The exact answer is

224/55 or 4 4/55

To estimate

Change the 56 to 55

55/5 *4/11

11*4/11

Canceling the 11's

4

Since we rounded the numerator down just a little, our estimate is a little low
