tolong dijawab beserta caranya yaaa makasih semua yg udh jawab

1) 3 - 8/9
= (3/1 × 9/9) - 8/9
= 27/9 - 8/9
= 19/9
= 2 1/9

2) 6 - 7/11
= (6/1 × 11/11) - 7/11
= 66/11 - 7/11
= 59/11
= 5 4/11

3) 4 ¾ - 3 5/12
= 4 + (¾×3/3) - 3 5/12
= 4 9/12 - 3 5/12
= 1 4/12
= 1 ¼

4) 7 6/10 - 2 ¹/5
= 7 6/10 - 2 + (1/5 × 2/2)
= 7 6/10 - 2 2/10
= 5 4/10
= 5 2/5

5) 4 5/6 - 1 2/9
= 4 + (5/6 × 3/3) - 1 + (2/9 × 2/2)
= 4 15/18 - 1 4/18
= 3 11/18
