1) 5 6/7 - 2 3/4 = 2) 7 8/9 - 2 5/6 = 3) 9 3/4 - 3 5/7 = 4) 8 3/7 - 3 2/3 = 5) 9 3/5 - 4 4/7 = Tolong Y karna Bsok dikumpul :)

1). 5 6/7 - 2 3/4 =
= (5×7+6)/7 - (2×4+3)/4
= 41/7 - 11/4
= 164/28 - 77/28
= 87/28

2). 7 8/9 - 2 5/6 =
= (7×9+8)/9 - (2×6+5)/6
= 71/9 - 23/6
= 426/54 - 207/54
= 219/54

3). 9 3/4 - 3 5/7 =
= (9×4+3)/4 - (3×7+5)/7
= 39/4 - 26/7
= 273/28 - 104/28
= 169/28

4). 8 3/7 - 3 2/3 =
= (8×7+3)/7 - (3×3+2)/3
= 59/7 - 11/3
= 177/21 - 77/21
= 100/21

5). 9 3/5 - 4 4/7 =
= (9×5+3)/5 - (4×7+4)/7
= 48/5 - 32/7
= 336/35 - 160/35
= 176/35

*maaf jika salah, semoga membantu ^_^
