    三年级下册两位数除法竖式计算题

    除法竖贺凳亩式

    五步骤:一商 二乘 三减四比较五落


    579除以4写成竖式形式把被除数579写在小厂房的里面,3写在小粗樱厂房的左边,小厂房表示除号的意思,后除的时候从高位除去

    第一步先用5除以4商禅森1

    第二步乘,商乘以除数1×4=4

    第三步减.5-4=1

    第四步比一比,用余数和除数比较 余数小于除数商要上去

    第五步落,落紧挨着5的后一位7,这样就是第三步的1和7合起来是17,落一次合起来,除一次

    重复以上五步骤,得出总数 144……3

    三年级口算除法800题

    三年级下册除法计算题 :

    69÷3=2386÷2=4348÷4=1284÷4=2163÷3=2139÷3=13

    56÷2=2896÷3=3222÷2=1188÷4=2266÷2=3344÷2=22

    除法是四则运算之一。已知两个因数的积与其中一个非零因数,求另一个因数衫晌的运算,叫做除法。

    两个数相除又叫做两个数的比。若ab=c(b≠0),用积数c和因数b来求另一个因数a的运算就是除法,写作c÷b,读作c除以b(或b除c)。其中,c叫做被除数,b叫做除数,运算的结果a叫做商。

    扩展资料:

    除法的运算性质:

    1、被除数扩大(缩小)n倍,除数不变,商也相应的扩大(缩小)n倍。

    2、除数扩大(缩小)n倍,被除数不变,商相应的缩小(扩大)n倍。

    被除数连颤斗续除以两个除数,等于除以这两个除数之积。有时可以根据除法的性质来进行简便运算。如:300÷25÷4=300÷(25×4)除以一个数就=这个数的倒数。

    三年级下册除法400道

    三年级下除法两位数除一位数的算法如下:

    两位数除以一位数(被除数各数位上的数都能被整除)的笔算方法:先用一位数去除两位数的十位上的数,商写在十位上;再用一位数去除两位数的个位上的数,商写在个位上。

    两位数除以一位数(被除数十位上的数不能被整除)的笔算方法:先用一位数去除两位数的十位上的数,商写在十位上;再把余数和个位上的数合并;仿败最后用除数去除,商写在个位上。验算方法:可以用乘法进行验算。顺口溜:两位除以一位数,先除首位记清楚。除完首位除个位,除到哪位商升大芦对齐。

    除法两位数除一位数举例:

    如:42÷2=?

    其实孩子没有学习笔算前,都能口算了,那笔算还会让孩子蒙圈的原因是因为没掌握方法。先把个位上的2盖住,42就变成4÷2就等于2,因为是除十位上的数所以商就写在十位上。然后再除个位上的2。再比如52÷2,同样盖住给位上的2,就变成5除以2商2余1,然后落个位上的2,组成12继续除,12除以2就等于6。

    这两道题相同的地方就是笔算的时候用到了两步,也就是十位、个位分别除;不同的地方是吵带42除以2十位可以除得完,而52除以2十位除不完,余数与个位合起来再继续除。
