    20道五年级上学期数学除法计算题!

    1、24.6-3.98+5.4-6.02

    解析:此题利用加法交换结合律,凑整再计算。步骤如下:

    24.6-3.98+5.4-6.02

    =(24.6+5.4)-(3.98+6.02)

    =30-10

    =20

    2、27×17/26

    解析:此题先用加法分配律,把27转换成激洞歼(26+1),再利用乘法结合律,使得运算简便。

    27×17/26

    =(26+1)×17/26

    =26×17/26+1×17/26

    =17+17/26

    =17又17/26

    3、528-99

    解析:利用凑整法和减法结合律计算,先利用凑整法把99变换为(100-1),再运用a-b-c=a-(b+c)来简便计算,步骤如下:

    528-99

    =528-(100-1)

    =528-100+1

    =428+1

    =429

    4、1.2×2.5+0.8×2.5

    解析:运用提取公因数的方法,公式:ac+ab=a(b+c),提取公因数2.5,1.2和0.8相加正好凑整数,使得运算简便。

    1.2×2.5+0.8×2.5

    =(1.2+0.8)×2.5

    =2×2.5

    =5

    5、2.96×40

    解析:此题先利用乘法分配律,把2.96×40转换成29.6x4,再利用乘明冲法结合律来简便计算。

    2.96×40

    =29.6x4

    =(30-0.4)x4

    =30×4+0.4×4

    =120-1.6

    =118.4

    6、0.36 x 1.5 - 0.45

    解析:此题运用乘法分配律,把0.45转换成1.5 x 0.3 ,即可提取公因数1.5,再根据乘法结合律进行简便计算。

    0.36 x 1.5 - 0.45

    = 0.36 x 1.5 - 1.5 x 0.3

    =1.5 × (0.36 - 0.3)

    =1.5 × 0.06颤悔

    = 0.09

    7、46×44/45

    解析:此题先利用加法分配律把46转换成(45+1),再利用乘法结合律:(a×b)×c=a×(b×c)使得运算简便。

    46×44/45

    =(45+1)×44/45

    =45×44/45+44/45

    =44+44/45

    =44又44/45

    8、1.6×7.5×1.25

    解析:此题利用乘法分配律把1.6,转化成2×0.8,再利用乘法结合律:(a×b)×c=a×(b×c)凑整,进行简便计算。

    1.6×7.5×1.25

    =2×0.8×7.5×1.25

    =(2×7.5)×(0.8×1.25)

    =15×1

    =15

    9、0.72×10.1

    解析:此题先利用加法分配律,把10.1转换成10+0.1,再利用乘法结合律使得运算简便。

    0.72×10.1

    =0.72×(10+0.1)

    =0.72×10+0.72×0.1

    =7.2+0.072

    =7.272
