Answer 3

To simplify the expressions, we can cancel out the common factors in the numerators and denominators:

1. 11/12 * 12/11 Here, 11/11 will cancel out, leaving us with: = 1

2. 13/14 * 14/13 The terms 13/13 will cancel out, leaving us with: = 1

3. 15/16 * 16/15 The terms 15/15 will cancel out, leaving us with: = 1

4. 17/18 * 18/17 The terms 17/17 will cancel out, leaving us with: = 1

5. 19/20 This expression cannot be simplified further.

So, the simplified forms of the given expressions are all equal to 1:

1. 11/12 * 12/11 = 1
2. 13/14 * 14/13 = 1
3. 15/16 * 16/15 = 1
4. 17/18 * 18/17 = 1
5. 19/20 = 19/20
