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。

2.46÷0.06= 32.4+2.6= 7.06-6.5= 0.38×0.25= 10.5÷0.21=

17.05+2.83= 4.56÷1.9= 9÷0.45= 1÷0.125=

2.85+1.05=

9-6.28=

0.08÷0.16= 26.81+5.29= 9.7+12.34=4.68÷1.2=0.32×1.05=6.24÷0.3= 1.8×5.04=10.2×6.7=3.25+15.7=36.7-12.9= 2.1×1.08=12÷0.24=1.92-0.71=梅州市癫痫病的治疗费用是多少 10-0.82=5.9-3.58= 81.9÷39= 0.28×3.04= 0.91×1.24=0.092÷23= 2.52÷1.8= 52.7×2.03= 1.7+12.85= 0.468÷1.2= 15.7-3.25=

二、递等式计算。 4.8×(3.5-2.1) ÷7= 18.75-0.23×2-4.54= (4.2+4.2÷2.1) ÷0.2= 17÷[(1.2+0.5) ×5]=4÷0.8-0.8÷4 = 8.59―4.1×0.1―4.59= 1.5×[1÷(2.1-2.05)]= [16.7-(6.2+9.5)] ×8.3 = 12.25+7.75-12.5+7.75= 9.4×[1.28-(1.54-0.31)]= (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?
