✔ 最佳答案
1)108 = 2 x 2 x 3 x 3 x 3
88 = 2 x 2 x 2 x 11
The largest number of children
= H.C.F. of 108 and 88
= 2 x 2
= 4
The least number of sweets each child gets
= 108/4
= 27
The least number of chocolates each child gets
= 88/4
= 22
2)
14 = 2 x 7
18 = 2 x 3 x 3
Least possible length of the square floor
= L.C.M. of 14 cm and 18 cm
= 2 x 7 x 3 x 3 cm
= 126 cm
3.
Method I:
6 = 2 x 3
108 = 2 x 3 x 2 x 3 x 3
12 = 2 x 3 x 2
x = 2 x 3 x 3 x 3 = 54
Method II:
The products of the two numbers = L.C.M. x H.C.F.
12x = 6 x 108
x = 54

001 的答案根本沒有回答問題，只做了一點翻譯，為甚麼會得這麼多票呢？除了造票、胡亂投票和投錯票之外，想不到其他厡因。
