直接寫(xiě)出得數(shù)． 1 2 × 1 4 =	5 18 ×3=	1 5 × 1 5 =	36× 2 9 =
4 9 ÷ 1 3 =	4 11 ÷4=	2 7 ÷ 3 7 =	10×10%=
2 9 ÷ 1 3 ÷ 2 3 =	8× 1 10 × 5 8 =	4× 1 9 + 8 9 ×4=

Answer 1

考點(diǎn)：分?jǐn)?shù)乘法,分?jǐn)?shù)除法

專題：運(yùn)算順序及法則

分析：運(yùn)用分?jǐn)?shù)乘除法的計(jì)算法則進(jìn)行計(jì)算，注意計(jì)算結(jié)果要化成最簡(jiǎn)分?jǐn)?shù)．

解答：

解： 1 2 × 1 4 = 1 8	5 18 ×3= 5 6	1 5 × 1 5 = 1 25	36× 2 9 =8
4 9 ÷ 1 3 =1 1 3	4 11 ÷4= 1 11	2 7 ÷ 3 7 = 2 3	10×10%=1
2 9 ÷ 1 3 ÷ 2 3 =1	8× 1 10 × 5 8 = 1 2	4× 1 9 + 8 9 ×4=4

點(diǎn)評(píng)：本題考查了分?jǐn)?shù)乘除法的計(jì)算法則，認(rèn)真計(jì)算即可．
