五年级小数乘法竖式计算题500题

五年级小数乘法竖式计算题500题同学们，小数乘法是五年级数学学习中的一个重要知识点，它不仅是整数乘法的延伸，也是后续学习更复杂数学知识的基础。熟练掌握小数乘法的竖式计算方法，能够帮助我们更准确、快速地解决实际问题。下面，我们将通过大量的竖式计算题练习，来巩固这一知识点。在开始练习之前，我们先来简要回顾一下小数乘法的计算要点，确保大家在练习时能够思路清晰。一、小数乘法计算要点回顾在进行小数乘法竖式计算时，我们可以按照以下步骤进行：首先，像计算整数乘法一样，忽略因数的小数点，将它们当作整数进行相乘，从最低位开始乘起，用第二个因数的每一位分别去乘第一个因数，再把所得的积相加。然后，数出两个因数中一共有几位小数。最后，在乘得的积的右边起数出几位，点上小数点。如果积的小数位数不够，要在前面用0补足，再点小数点。大家在计算时一定要注意，积的小数点位置不能点错哦！二、专项练习题库（一）一位小数乘一位小数1.1.2×3.4=2.2.5×1.6=3.0.8×0.9=4.3.6×2.1=5.4.7×0.5=6.5.3×1.2=7.0.7×6.8=8.7.2×0.4=9.8.1×3.5=10.0.6×0.7=11.2.2×4.4=12.3.3×0.3=13.5.5×2.2=14.6.4×1.1=15.0.9×8.8=16.4.1×5.5=17.7.7×0.2=18.8.9×3.3=19.0.5×0.5=20.1.8×6.2=21.2.9×4.1=22.3.7×0.8=23.5.1×2.5=24.6.6×1.8=25.0.4×9.3=26.7.3×3.7=27.8.2×0.6=28.9.5×4.4=29.0.3×0.8=30.1.5×7.1=31.2.3×5.8=32.3.8×2.4=33.4.9×0.7=34.6.3×1.3=35.0.2×8.5=36.7.8×3.1=37.8.6×0.9=38.9.1×4.6=39.0.1×0.4=40.1.3×5.2=41.2.6×4.8=42.3.9×2.7=43.5.4×0.6=44.6.7×1.5=45.0.8×7.6=46.7.1×3.8=47.8.3×0.5=48.9.2×4.2=49.0.7×0.3=50.1.7×6.3=（二）一位小数乘两位小数1.2.3×4.56=2.5.6×0.78=3.0.9×12.3=4.6.7×8.91=5.3.4×0.56=6.7.8×2.34=7.1.2×34.5=8.8.9×0.12=9.4.5×6.78=10.0.6×9.87=11.3.2×5.43=12.6.5×0.43=13.9.1×2.12=14.0.7×8.76=15.5.3×1.09=16.8.2×0.34=17.2.1×4.55=18.7.6×6.77=19.0.5×11.2=20.4.1×0.89=21.6.3×3.21=22.9.8×0.55=23.3.3×7.89=24.0.8×2.31=25.5.7×4.02=26.8.5×0.67=27.2.4×1.23=28.7.1×5.67=29.0.4×9.12=30.5.8×0.21=31.3.5×8.76=32.7.9×0.98=33.1.1×6.54=34.8.8×2.01=35.0.3×7.65=36.6.2×3.45=37.9.3×0.44=38.2.7×5.61=39.0.2×1.89=40.5.9×6.78=41.4.6×0.76=42.8.3×2.34=43.0.1×8.9=44.7.3×4.56=45.3.1×0.12=46.9.5×5.67=47.2.8×3.45=48.6.4×0.88=49.0.9×2.11=50.5.1×7.89=51.7.2×0.56=52.3.6×4.55=53.8.4×1.23=54.0.4×6.77=55.6.1×2.34=56.9.2×0.34=57.2.5×5.43=58.7.7×0.43=59.0.6×3.21=60.5.4×8.76=61.3.8×1.09=62.8.6×0.55=63.1.3×7.89=64.0.7×2.31=65.6.8×4.02=66.9.4×0.67=67.2.9×1.23=68.7.4×5.67=69.0.5×9.12=70.5.2×0.21=71.4.2×8.76=72.8.1×0.98=73.1.4×6.54=74.9.7×2.01=75.0.3×7.65=76.6.9×3.45=77.9.6×0.44=78.3.9×5.61=79.0.8×1.89=80.5.5×6.78=（三）两位小数乘两位小数1.1.23×4.56=2.0.78×0.65=3.2.34×5.67=4.8.91×0.12=5.3.45×6.78=6.0.56×7.89=7.4.56×1.23=8.9.87×0.65=9.5.67×2.34=10.0.12×8.91=11.6.78×3.45=12.7.89×0.56=13.2.12×3.33=14.4.44×0.22=15.5.55×6.66=16.0.77×8.88=17.3.21×1.11=18.6.54×0.99=19.7.65×2.22=20.0.88×4.44=21.1.09×5.55=22.3.03×0.77=23.6.06×7.07=24.0.91×8.08=25.2.02×9.09=26.5.05×0.11=27.8.08×2.02=28.0.33×3.03=29.4.04×4.04=30.7.07×0.55=31.1.21×6.06=32.3.32×0.88=33.5.53×9.09=34.0.22×1.12=35.4.43×2.23=36.6.64×0.33=37.7.75×3.34=38.0.44×5.55=39.8.86×4.45=40.9.97×0.66=41.1.31×6.67=42.2.42×0.77=43.3.53×7.78=44.0.88×8.89=45.4.64×2.92=46.5.75×0.11=47.6.86×3.03=48.0.55×4.14=49.7.97×5.25=50.8.08×0.66=51.1.41×6.36=52.2.52×0.77=53.3.63×7.47=54.0.88×8.58=55.4.74×2.69=56.5.85×0.22=57.6.96×3.73=58.0.66×4.84=59.7.07×5.95=60.8.18×0.33=61.1.51×6.46=62.3.54×0.99=63.5.56×7.57=64.0.77×8.68=65.4.84×2.79=66.6.96×0.44=67.7.17×3.83=68.0.88×4.94=69.8.28×5.05=70.9.39×0.55=71.1.61×6.56=72.2.72×0.66=73.3.83×7.67=74.0.99×8.78=75.4.94×2.89=76.5.05×0.77=77.6.16×3.93=78.0.11×5.05=79.7.27×6.06=80.8.38×0.88=（四）小数乘整十、整百数1.2.5×20=2.3.6×30=3.0.45×40=4.5.6×50=5.6.7×60=6.0.78×70=7.8.9×80=8.9.1×90=9.1.23×100=10.2.34×200=11.3.45×300=12.0.56×400=13.4.56×500=14.5.67×600=15.0.67×700=16.6.78×800=17.7.89×900=18.0.89×1000=19.8.91×20=20.9.87×30=21.0.12×40=22.1.23×50=23.2.34×60=24.0.34×70=25.3.45×80=26.4.56×90=27.0.56×100=28.5.67×200=29.6.78×3
