五年级上学期计算练习小数乘除法简便运算[1].docx

五年级上册计算练习（竖式练习）留意：列竖式计算时小数乘法,肯定要数清两个因数共有的小数位数,再确定积的小数位数,然后再去掉里面的O小数除法里，必需将除数化成整数后再依据法则计算.，商的小数点和转化后的被除数小数点对齐一、把卜.列各式转化成除数是整数的除法。O.38.373.8190.469.3840.161.36二、列竖式计算下列各题0.2132.34O.078O.120.96661.8756(1)9÷36(2)7.218÷36(3)5.93X0.76(保留三位小数）(4)7.2÷5(5)16.32÷51(6)25÷0.38(保留到百分位）(7)4÷1.2(8)0.56÷1.4(9)30÷74(商用循环小数表示）(10)96÷15(11)2.7+3.13(12)1.7÷11(商用循环小数表示）(13)40.4÷8(14)4.7X0.23(15)141.2-48.98(验算）(16)13÷2.4(17)58.89÷13(18)0.448÷0.28(验算）(19)4.4÷50(20)7.2×6.25(21)8.9X0.36(22)3.25X8(23)7.2÷0.48(24)78.92+115.8(25)3-2.08(26)32÷0.016(27)40.5÷18(验算)(28)28×2.05(29)179.2÷64(30)0.945÷0.035(31)18-5.29(32)7.45÷3.8(33)1.21X18(验算)(34)9.6÷1.6(35)2.1.÷0.25(36)5.85÷0.015(37)5.06×13(38)3.52÷5.5(39)0.957÷4.65(40)75.6÷18(41)50.34÷14(42)0.832÷0.26(43)0.73+12(44)O.43÷8.6(45)3.85X0.014(46)96÷O.64(47)8.68÷6.2(48)3.952÷0.76(49)50÷O.25(50)0.465÷15(51)9.72÷0.027(52)50.4÷48(53)4.95÷3.3(54)18.27÷2.1(55)3.54X13(56)O.69×8.4(57)97.2÷0.18(58)64.8÷24(59)6.5×0.48(60)7.4+12.86(61)64.8÷19(62)179.2÷64(63)5.84÷0.16(64)40÷0.32(65)90-16.75(66)7.04÷4.07(67)3.52÷55(68)20-5.674(69)1.872÷2.4(70)179.2÷64(71)2.03×4.7(72)0.36X0.24(73)3.56+7.5(74)1.9×(76)4.32÷3.6(77)6.48÷0.8(78)5.4÷0.036(79)2.4×1.02(80)O.26÷4.5(81)4.75÷0.05(82)8.32×2.5(83)3.27×O.64(84)0.282÷4.7(85)32.9÷9.4(86)31.28×1.6(87)8.62÷0.43(88)9.8×0.85(89)67.2÷0.42(90)3.06X12计算练习（简便计算）(1)70÷28(2)2.31X1.2X0.5(3)12.78-(4.97+2.78)(7)2.7÷45(8)3.12+3.12×99(9)34.82-(4.82+15.2)(10)8.9×9.9(11)1.25×32×12.5(12)17.85-(2.96+5.85)(13)6.3÷1.4(14)2.5×3.2×12.5(15)4.61+5.8+4.2+6.39(16)1.25×88(17)382÷12.5÷0.8(18)4.6×0.35+4.6×0.65(19)O.85×99(20)132-43.7-56.3(21)O.95×X0.95(22)13÷12.5(23)0.8+0.88+0.22(24)2.4××O.87(25)2.4×102(26)1.63+2.37÷×(28)4.5÷1.8(29)9.43×101-9.43(30)4.8+8.63+5.2+0.37(31)4.2÷3.5(32)10.9-3.74+0.9(33)1.29+3.7+2.71+6.3(34)4.9÷1.4(35)15.17-6.8-3.2(36)(37)2.5×2.4(38)15.17-6.8-3.2(39)3.2+0.36+4.8+1.64(40)15÷O.25(41)3.1+25.78+6.9(42)1.23+3.4-0.23+6.6(43)4.8÷9.9(44)2.95×101-2.95(45)1.28X8.6+0.72×8.6(46)0.25×36(47)0.25×(O.4+40)(48)9.16××9.16×32.4(52)5.6÷3.5(53)9.73÷12.5÷0.8(54)0.125×0.25×0.5X64(55)9.4×9.94+4.68÷0.25(56)888×16÷222×36(57)15.32×(58)6.3÷2.8×9.9+0.17(59)6.02+3.6+1.98(60)4.25÷2.5(61)6.1×0.983.6+3.6×3.91(62)12.5×O.96×O.8(63)6.09×(64)1.25×3.2×0.35(67)3.2×10.1(70)0.52×105(73)O.32×403(75)1.34+1.8+3.66+0.2(76)0.85×199(79)930÷0.6÷5(81)1.27+3.9+0.73+16.1(66)42×43.43-43×42.42(68)15÷(0.15×0.4)(71)28.6××(74)7.67-2.57-2.43(77)0.8×65.18×1.25(80)5.86-0.72+0.38(82)17.2×10.11.9+31.4×0.81(83)63×10.1-63×O.1(84)3.14×(85)84÷O.42÷2(5-0.68)÷1.2(86)(12.6+4.8)÷0.6(87)0.8×(88)5.62X1.01(90)45.55-(6.8215.45)(89)6.8+1.25×6.8X8(91)930÷5÷0.6-1.91+5.09×22.8(97)2.5×(13×4)(98)3.07-0.38-1.62(99)5.4×0.68+3.4×2×0.16(100)28.9×4÷289(101)0.8×(4.3×1.25)(102)3.25÷1.79-0.59+1.75(103)0.25×8.5×4(104)(2.5-0.25)×0.4(105)0.86××14.7(106)4.2×99+4.2(107)O.125×0.5×8×4(108)27.8×5.64+72.2×5.64(109)4×4.16×2.5(110)(7.7+1.54)÷0.7÷2.5÷0.4(112)25-4.7+5.3(113)7.3÷4+2.7×0.25(114)0.666×O.7+0.222×O.9(115)9.4+0.3-6.4(116)0.29×46+0.29××0.5(119)3.1+(25.78+6.9)(120)3.25+1.83+0.75+2.17(121)6.82÷4÷0.25(1.2+1.3)÷0.25(124)13.8÷0.25÷4(126)0.83+0.69+0.17+10.31(127)63÷0.35÷0.4(129)12.83+2.25+1.75+6.17(130)7.5+4.9-6.5(132)15.25+4.72-4.75+5.28(122)7.5×2.1.+78×0.79(123)9.4÷(125)6.75-(0.9+3.75)(128)18.75+9.24-8.75(131)16.79-2.87+2.13(133)8-2.45-1.55(134)1.26÷(1.26×0.8)(140)1.57+0.245+7.43(139)3.9÷(1.3×5)(141)35.7-4.9-(5.72+5.1)(142)0.25×0.73×4(144)4.58+2.39+(5.42+7.61)(145)12.7-4.8-5.2(146)36.54-1.76-4.54(143)12.7-(3.7+0.84)(147)2.55×1.5+1.5+6.45×1.5(148)10-2.57-6.430.7+0.1111×2.1(151)6.3+4.82+3.7(150)0.7777×(149)7.6×0.8+0.2×7.6(153)2.35+1.713+0.287+7.65(154)3.67X99+3.67(155)0.35×1.25×2×0.8(156)2.5×7.5+7.5×6.4+0.75(157)12.8-4.9-5.1(158)5.14÷O.25+4.6×4(159)0.134+2.66+0.866(160)2.43X99+2.43(161)1.01×8.8-0.088(162)8.23+4.5-8.23+4.5(163)4.7×1.25×1.6(164)2.8×0.5+0.5×27.2(165)1.8×O.9+0.18(166)1.25×64×0.25(167)4.3+1.4+25.7+8.6(168)7.8×4.86÷3.9(169)4.18+4.18X(172)0.4×0.7×0.25(173)0.5×0.08÷0.5××0.08(174)12.5×9.6(152)(4.23+6.17)×0.8(175)8.4×0.2+1.6×0.2(176)0.2×3÷0.2×3(I77)O.75X102(181)6393-1.93-0.84(182)5.649+7.8-3.8(183)6.3+9.8-6.3+9.8(184)84÷0.42÷
