Selesaikan operasi hitung pecahan berikut!

1. 2/3 + 3/4 - 1/6 = 8/12 + 9/12 - 2/12 = 15/12 = 1 3/12

2. 9/10 - 2/5 + 3/4 = 18/20 - 8/20 + 15/20 = 25/20 = 5/4 = 1 1/4

3. 1 3/5 + 2 1/6 - 1/2 = 8/5 + 13/6 - 1/2 = 48/30 + 65/30 - 15/30 = 98/30 = 3

8/30 = 3 4/15
4. 2 2/3 + 4 3/5 - 4/15 = (2 + 4) + 2/3 + 3/5 - 4/15 = 6 + 10/15 + 9/15 - 4/15 =

6 15/15 = 7

5. 8 8/9 - 2 1/6 - 1/2 = 80/9 - 13/6 - 1/2 = 160/18 - 39/18 - 9/18 = 112/18 = 6
