1. 6/14 ÷ 2 4/7 × 9/81 = 2. 23 1/2 + 2 6/10 - 5 3/5 = 3. 2/9 + 5/10 - 1/10 ÷1/7 = 4. 5 1/7 × 3 8/9 × 3/6 = Tolong ya. Makasih...

1. 6/14 x 7/18 x 9/81 = 6/4
2. 47/2 + 26/10 - 28/5= 105/10 di jadikan pecahan sederhana 1 5/105 = 1 1/21
3. 2/9+5/10-(7/10:/7/1) =7/10
2/9+5/10-7/10= 2/90 (disederhanakan) = 1/45
4. 36/7 x 35/9 x 3/6 = 2/1 = 2
Semoga membantu
