Answer 1

考點(diǎn)：百分?jǐn)?shù)的加減乘除運(yùn)算

專(zhuān)題：運(yùn)算順序及法則

分析：根據(jù)分?jǐn)?shù)乘法和分?jǐn)?shù)除法的計(jì)算方法進(jìn)行計(jì)算即可，計(jì)算時(shí)把百分?jǐn)?shù)化為小數(shù)．

解答：

解： 5 6 × 9 10 = 3 4	5 9 ÷ 5 6 = 2 3	8×12.5%=1	3 8 -0.37=0.005	1÷10%=10
2.5×40%=1	2÷3× 3 4 = 1 2	11× 3 22 +10=11.5	2 3 - 2 3 × 3 4 = 1 6	18÷ 3 4 ×75%=18

點(diǎn)評(píng)：本題考查的是分?jǐn)?shù)的基本運(yùn)算，解答時(shí)注意先算乘除，后算加減．
