Answer 2

Let's solve each of these expressions step by step:

1. 8/13 - 6/13: To subtract fractions with the same denominator, you simply subtract the numerators while keeping the denominator the same. In this case, we have:

(8/13) - (6/13) = (8 - 6)/13 = 2/13

2. 8/13 - 2/133: Since the denominators are different, we need to find a common denominator. The least common multiple (LCM) of 13 and 133 is 13 × 133 = 1729. Then, we can rewrite the fractions with the common denominator:

(8/13) - (2/133) = (8 × 133)/(13 × 133) - (2 × 13)/(133 × 13) = 1064/1729 - 26/1729 = (1064 - 26)/1729 = 1038/1729

3. 9/13 + 2/13: To add fractions with the same denominator, you simply add the numerators while keeping the denominator the same. In this case, we have:

(9/13) + (2/13) = (9 + 2)/13 = 11/13

4. 10/13 - 3/13: Similar to the first example, we have the same denominators:

(10/13) - (3/13) = (10 - 3)/13 = 7/13

5. 7/13 - 5/13: Again, we have the same denominators:

(7/13) - (5/13) = (7 - 5)/13 = 2/13

6. 5/13 + 1/13: Once more, we have the same denominators:

(5/13) + (1/13) = (5 + 1)/13 = 6/13

7. 3/13 + 4/13: Same denominators:

(3/13) + (4/13) = (3 + 4)/13 = 7/13

8. 5/13 + 5/13: Once again, the denominators are the same:

(5/13) + (5/13) = (5 + 5)/13 = 10/13

So, the results are:

1. 2/13
2. 1038/1729
3. 11/13
4. 7/13
5. 2/13
6. 6/13
7. 7/13
8. 10/13
