專(zhuān)題：計(jì)算題

分析：按照分?jǐn)?shù)四則計(jì)算的計(jì)算法則和混合運(yùn)算的運(yùn)算順序直接計(jì)算得出答案即可．

解答：

解： 1 5 + 4 5 =1	3 4 - 1 4 = 1 2	2 5 ×3= 6 5	3 7 × 1 3 = 1 7	1 2 ÷60%= 5 6
1 2 × 2 3 = 1 3	1 7 ×14=2	4 11 ÷4= 1 11	3 5 ÷ 1 5 =3	1 6 + 1 6 ÷ 1 6 + 1 6 =1 1 3

點(diǎn)評(píng)：掌握四則計(jì)算的計(jì)算法則和運(yùn)算順序是解決問(wèn)題的關(guān)鍵．
