Answer 2

It looks like you've provided three numerical expressions. Let's break them down:

1. 1-2/7: This is a subtraction operation. Start with 1 and subtract 2/7 from it. Result: 1 - 2/7 = 5/7

2. 3 8/11: This seems to be a mixed number, with 3 as the whole part and 8/11 as the fractional part. Result: 3 8/11 (This is already in its simplest form.)

3. 6-2 1/3: Another subtraction operation. Start with 6 and subtract 2 1/3 from it. To subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 3. 2 1/3 can be written as an improper fraction: (2 * 3 + 1) / 3 = 7/3. Now we can subtract: 6 - 7/3. To subtract fractions, they need a common denominator. The common denominator for 3 and 3 is 3. 6 = 18/3, so the expression becomes 18/3 - 7/3 = 11/3.

   Mixed number form: 11/3 can be written as a mixed number: 3 2/3.

So, the results of the expressions are:

1. 1-2/7 = 5/7
2. 3 8/11 (already in simplest form)
3. 6-2 1/3 = 3 2/3
