Answer 2

а) 6 1/8

To add 6 and 1/8, we simply add the whole number part (6) to the fraction part (1/8).

6 + 1/8 = 6 1/8

б) 5 9/10 + 2 7/10

To add 5 9/10 and 2 7/10, we add the whole number parts (5 and 2) separately and then add the fraction parts (9/10 and 7/10) separately.

5 + 2 = 7

9/10 + 7/10 = 16/10 = 1 6/10 = 1 3/5

So, 5 9/10 + 2 7/10 = 7 3/5

в) 3 2/9 + 6/9

To add 3 2/9 and 6/9, we add the whole number part (3) to the whole number part (0) of the fraction and then add the fraction parts (2/9 and 6/9) together.

3 + 0 = 3

2/9 + 6/9 = 8/9

So, 3 2/9 + 6/9 = 3 8/9

г) 1 15/12 - 2/12

To subtract 2/12 from 1 15/12, we subtract the fraction part (2/12) from the whole number part (1) and the fraction part (15/12).

1 - 2/12 = 1 - 1/6 = 6/6 - 1/6 = 5/6

15/12 - 2/12 = 13/12

So, 1 15/12 - 2/12 = 5/6 + 13/12 = 18/12 = 1 6/12 = 1 1/2

д) 3 1/14 - 1 + 3/14

To subtract 1 and 3/14 from 3 1/14, we subtract the whole number part (1) and the fraction part (3/14) separately.

3 - 1 = 2

1/14 - 3/14 = -2/14 = -1/7

So, 3 1/14 - 1 + 3/14 = 2 - 1/7 = 13/7 - 1/7 = 12/7 = 1 5/7

e) 8 - 9/80

To subtract 9/80 from 8, we subtract the fraction part (9/80) from the whole number part (8).

8 - 9/80 = 8 - 0.1125 = 7.8875

So, 8 - 9/80 = 7.8875

I hope this helps! Let me know if you have any further questions.
