1. 8 2/3 - 6 1/7 = 2. 3/9 : 5/6 = 3. 4 2/5 × 2 2/3= 4.3 2/5 × 2 1/4 = 5. 0,4 : 0,2 = 6.3 1/4 × 2 1/3 × 3 2/5 = Cepet dijawab dikumpulin besok Pakai cara

1) 8 2/3 - 6 1/7 = 26/3 - 43/7 = 182-129/21 = 53/21 = 2 11/21
2) 3/9 ÷ 5/6 = 3/9 × 6/5 = 18/45 = 2/5
3) 4 2/5 × 2 2/3 = 22/5 × 8/3 = 176/15 = 11 11/15
4) 3 2/5 × 2 1/4 = 17/5 × 9/4 = 153/20 = 7 13/20
5) 0,4 ÷ 0,2 = 4/10 ÷ 2/10 = 4/10 × 10/2 = 2
6) 3¼ × 2⅓ × 3 2/5 = 13/4 × 7/3 × 17/5 = 1547/60 = 25 47/60

no 2 (kurang jelas)
3/6 : 5/6 =3/6 × 6/5
aku pake cara yg di coret :v
maaf kalau ada yang salah
