五年级小数乘法100道强化练习试题

五年级小数乘法100道强化练习试题小数乘法是五年级数学学习中的重要一环，它不仅是整数乘法的延伸，更是后续学习更复杂数学知识的基础。熟练掌握小数乘法的计算方法，能够有效提升孩子们的计算能力和数感。下面为同学们精心准备了100道小数乘法强化练习题，希望通过系统的练习，大家能够攻克小数乘法的难点，做到算得又快又准。一、温馨提示在进行小数乘法练习前，请同学们牢记以下计算要点：1.先按照整数乘法的法则算出积；2.再看因数中一共有几位小数，就从积的右边起数出几位，点上小数点；3.如果积的小数位数不够，要在前面用0补足，再点小数点；4.积的末尾有0时，一般要把0去掉（除非题目有特殊要求保留小数位数）。计算时一定要仔细、认真，看清数字和小数点的位置哦！二、练习题第一组：基础巩固（一位小数乘一位小数）1.0.2×0.3=2.0.5×0.8=3.0.1×0.9=4.0.4×0.4=5.0.6×0.7=6.0.9×0.2=7.0.3×0.6=8.0.7×0.5=9.0.8×0.1=10.0.2×0.7=11.0.5×0.5=12.0.3×0.9=13.0.6×0.2=14.0.8×0.4=15.0.4×0.7=16.0.9×0.5=17.0.1×0.6=18.0.7×0.8=19.0.2×0.9=20.0.3×0.3=第二组：能力提升（一位小数乘两位小数/整数乘小数）21.0.3×0.12=22.2.5×0.4=23.0.15×0.6=24.6×0.08=25.0.45×0.2=26.1.2×0.3=27.0.07×0.8=28.0.8×1.5=29.3×0.24=30.0.65×0.1=31.0.4×0.36=32.5×0.18=33.0.22×0.5=34.0.9×0.04=35.7×0.5=36.0.13×0.3=37.0.5×0.48=38.8×0.12=39.0.35×0.2=40.0.06×0.9=第三组：深化练习（两位小数乘一位小数/小数乘整数）41.0.12×0.5=42.0.36×2=43.0.08×0.4=44.1.25×0.8=45.0.28×0.3=46.0.45×4=47.0.09×0.7=48.2.4×0.2=49.0.55×0.1=50.0.16×5=51.0.04×0.25=52.3.6×0.1=53.0.72×0.2=54.0.18×3=55.0.05×0.16=56.4.5×0.02=57.0.25×0.4=58.0.03×0.6=59.6.2×0.3=60.0.88×0.1=第四组：综合应用（小数位数多样）61.0.25×0.04=62.1.02×0.3=63.0.48×0.5=64.0.07×1.2=65.2.2×0.11=66.0.33×0.3=67.0.56×0.02=68.1.5×0.08=69.0.09×0.12=70.0.6×0.65=71.0.75×0.4=72.0.08×0.15=73.1.2×1.2=74.0.44×0.05=75.0.19×0.2=76.0.03×0.07=77.3.2×0.25=78.0.5×0.52=79.0.11×0.11=80.0.8×0.005=第五组：拓展挑战（积的小数位数及验算意识）81.0.025×0.4=82.1.25×0.08=83.0.62×0.3=84.0.04×0.18=85.2.1×0.12=86.0.38×0.05=87.0.09×0.002=88.1.05×0.2=89.0.4×0.46=90.0.006×0.5=91.0.72×0.15=92.0.28×0.04=93.3.5×0.002=94.0.102×0.3=95.0.055×0.2=96.0.8×0.105=97.0.012×0.6=98.0.45×0.008=99.0.07×0.013=100.1.1×0.101=三、参考答案做完所有题目后，同学们可以对照下面的答案进行核对。如果发现错误，一定要认真分析原因，及时订正哦！1.0.062.0.43.0.094.0.165.0.426.0.187.0.188.0.359.0.0810.0.1411.0.2512.0.2713.0.1214.0.3215.0.2816.0.4517.0.0618.0.5619.0.1820.0.0921.0.03622.123.0.0924.0.4825.0.0926.0.3627.0.05628.1.229.0.7230.0.06531.0.14432.0.933.0.1134.0.03635.3.536.0.03937.0.2438.0.9639.0.0740.0.05441.0.0642.0.7243.0.03244.145.0.08446.1.847.0.06348.0.4849.0.05550.0.851.0.0152.0.3653.0.14454.0.5455.0.00856.0.0957.0.158.0.01859.1.8660.0.08861.0.0162.0.30663.0.2464.0.08465.0.24266.0.09967.0.011268.0.1269.0.010870.0.3971.0.372.0.01273.1.4474.0.02275.0.03876.0.002177.0.878.0.2679.0.012180.0.00481.0.0182.0.183.0.18684.0.007285.0.25286.0.01987.0.____88.0.2189.0.18490.0.00391.0.10892.0.011293.0.00794.0.030695.0.01196.0.08497.0.0072
