✔ 最佳答案
1) 4-1/3 = 12/3 - 1/3 = 11/3 = (3又3分之2)2) 5- 2/7 = 35/7-2/7 = 33/7 = (4又7分之5)
3) 1/6 + 7/10 = 5/30 + 21/30 = 26/30 = 13/15
4) 6又5分之1-7又10分之9+2又2分之1 = 31/5 - 79/10 + 5/2 = 62/10 - 79/10 + 25/10 = 8/10 = 4/5
5) 2又4分之1+9分之7-1又3分之1= 9/4 + 7/9 - 4/3 = 81/36 + 28/36 - 48/36 = 61/36 = 1又36分之25

1. 4 - 1/3 = 3又3/3 - 1/3 = 3又2/3
2. 5 - 2/7 = 4又7/7 - 2/7 = 4又5/7
3. 3又1/6 + 7/10 = 3又5/30 + 21/30 = 3又26/30 = 4又13/15
4. 6又1/5 - 7又9/10 + 2又1/2 = 7又9/10 - 6又2/10+ 5/10 = 1又11/10 = 2又1/10
5. 2又1/4 + 7/9 - 1又1/3 = 2又9/36 + 28/36 - 1又12/36 = 1又25/36
(可能有少少問題)
2. 5 - 2/7 = 4又7/7 - 2/7 = 4又5/7
3. 3又1/6 + 7/10 = 3又5/30 + 21/30 = 3又26/30 = 4又13/15
4. 6又1/5 - 7又9/10 + 2又1/2 = 7又9/10 - 6又2/10+ 5/10 = 1又11/10 = 2又1/10
5. 2又1/4 + 7/9 - 1又1/3 = 2又9/36 + 28/36 - 1又12/36 = 1又25/36
