篇二:小数加减乘除混合运算训练题
小数加减乘除及混合运算专项训练
小数加减法(竖式计算方法):相同数位对齐(小数点对齐),从低位算起。

小数乘法:(竖式计算方法):末位对齐,按整数计算,积的小数位数等于各因数的小数位数的和。

小数除法:(竖式计算方法):(1)小数除以整数:先除整数部分,整数部分不够除商“0”,一位一位的计算,除不尽是补“0”再算。

(2)小
数除以小数:按商不变规律化除数为整数,然后按小数除以整数计算。

混合计算:(递等式计算,又称脱式计算)先算乘除,再算加减,有括号的先算括号里面的,如果有中括号,先算里面的小括号。

)一、竖式计算。

0.31)]=(6.1-4.6)÷0.8×0.4=3.6×4.25÷3.6×4.25=
三、列式计算。

(必须是递等式计算)
(1)9.6里有多少个0.16?(2)4.86与3.27的差是0.25的多少倍?
(3)5.18除以4与9.25的积商是多少?(4)23的十分之一与7.9的一半的和是多少?
(5)8.4加上8.4与1.6的差,所得的和除以4,(6)用10减去6.8的差去除24.8,商是多少?商是多少?
(7)6.2减去2.4与1.3的和,除以1.25的(8)4.8与2.7的和乘5.02,积是多少?
商是多少?
(9)35.7除以0.7的商,加上12.5与的积,(10)10.2减去2.5的差,除以0.35与24.8的积,和是多少?商是多少?
