1.3 1/13 × 5 3/15 = 2.10÷4 3/8= 3.9/14÷ 3 3/6=

1. 3 1/13 × 5 3/15 = 40/13 × 78/15 = 3120/195 = 16
2. 10 : 4 3/8 = 10/1 : 35/8 = 10/1 × 8/35 = 16/7 = 2 2/7
3. 9/14 : 3 3/6 = 9/14 : 21/6 = 9/14 × 6/21 = 18/98 = 9/49

^^Maaf kalau salah^^
^^Semoga membantu^^

1.3 1/13 × 5 3/15 = 40/13 × 78/15 = 48/3=16
2.10 ÷ 4 3/8 = 10 × 8/35 = 16/7 = 2 2/7
3.9/14 ÷ 3 3/6 = 9/14 × 6/21 = 9/49
maaf kalo ada yang salah
