首先,將7同11通分,
=44/77+21/77=65/77
,再將7乘以11=66/77
再將65/77+66/77=131/77=1 54/77
因為要減1/2,所以要將1 54/77乘以2,變成雙數,
=108/154
咁就可以減1/2喇
108/154-1/2
=108/154-77/154
=31/154
=44/77+21/77=65/77
,再將7乘以11=66/77
再將65/77+66/77=131/77=1 54/77
因為要減1/2,所以要將1 54/77乘以2,變成雙數,
=108/154
咁就可以減1/2喇
108/154-1/2
=108/154-77/154
=31/154

4/7+3/11+6/7-1/2
= 88/154 + 42/154 + 132/154 - 77/154
= (88+42+132-77)/154
= 185/154
= 88/154 + 42/154 + 132/154 - 77/154
= (88+42+132-77)/154
= 185/154

88 / 154 + 42 /154 + 132/ 154 - 77 / 154
= 185 / 154
= 185 / 154
