265道口算题,5年级下册的最好是分数加减法~

600道五年级下下册数学加减 小数加减乘除 分数加减混合运算 小数加减乘除混合运算

常见以下几类题型:
一、运用加法结合律进行简算
(a+b)+c=a+(b+c) 或a+b+c+d=(a+c)+(b+d)
例1、5.76+13.67+4.24+6.33
=(5.76+4.24)+(13.67+6.33)
=10+10
=20
例2、37.24+23.79-17.24
=37.24-17.24+23.79
=20+23.79
=43.79
二、运用乘法结合律进行简算:这种题型往往含特殊数字之间相乘
(a×b)×c=a×(b×c)
特殊数字之间相乘:
25×4=100 125×8=1000 25×8=200 125×4=500
例3、 4×3.78×0.25
=4×0.25×3.78
=1×3.78
=3.78
例4、 125×246×0.8
=125×0.8×246
=100×246
=24600
2.5×0.125×8×4等,如果遇到除法同样适用,或将除法变为乘法来计算。如:8.3×67÷8.3÷6.7等。
三、利用乘法分配律进行简算:
(a+b)×c=a×c+ b×c
(a-b)×c=a×c- b×c
做这种题,一定不要急着去算,先要分析各数字之间的特殊关系。也就是先要仔细观察,找到做题的窍门。
例5、(2.5+12.5)×40
=2.5×40+12.5×40
=100+500
=600
例6、3.68×4.79+6.32×4.79
=(3.68+6.32)×4.79
=10×4.79
=47.9
例7. 26.86×25.66-16.86×25.66
=(26.86-16.86) ×25.66
=10×25.66
=256.6
例8、 5.7×99+5.7
= 5.7×(99+1)
=5.7×100
=570
运用乘法分配律进行简算,遇到除以一个数,先化为乘以一个数的倒数,再分配。
如:2.5×(100+0.4),还应注意,有些题目是运用分配律的逆运算来简算:即提取公因数。如:0.93×67+33×0.93。
四、利用加减乘除把数拆分后再利用乘法分配律进行简算:
例9、34×9.9
=34×(10-0.1)
=34×10-34×0.1
=340-3.4
=336.6
例10、 57×101
=57×(100+1)
=57×100+57×1
=5757
例11、7.8×1.1
=7.8×(1+0.1)
=7.8×1+7.8×0.1
=7.8+0.78
=8.58
例12、25×32
=25×4×8
=100×8
=800
例13、125×0.72
=125×8×0.09
=1000×0.09
=90
例14、87×2/85
=(85+2) ×2/85
=85×2/85+2×2/85
=2+4/85
=2又4/85
五、连减与连除
a-b-c=a-(b+c)
a÷b÷c=a÷(b×c)
例15、56.5-3.7-6.3
=56.5-(3.7+6.3)
=56.5-10
=46.5
例16、32.6÷0.4÷2.5
=32.6÷(0.4×2.5)
=32.6÷1
=32.6
六、需要变形才能进行的简便运算:做这一类题,要先观察,找出规律,然后变形后进行简算。
例16、86.7×0.356+1.33×3.56
=8.67×3.56+1.33×3.56
=(8.67+1.33)×3.56
=10×3.56
=35.6
例17、15.6÷4-5.6×1/4
=15.6×1/4-5.6×1/4
=(15.6-5.6)×1/4
=10×1/4
=2又1/2
例18、16/23×27+16×19/23
=27/23×16+16×19/23
=16×(27/23+19/23)
=16×2
=32
七、接近整百的数的运算。这种题型需要拆数、转化等技巧配合。
如;302+76=300+76+2,298-188=300-188-2,等。
八、认真观察某项为0或1的运算。
如:7.93+2.07×(4.5-4.5)等。
总的说来,简便运算的思路是:(1)运用运算的性质、定律等。(2)可能打乱常规的计算顺序。(3)拆数或转化时,数的大小不能改变。(4)正确处理好每一步的衔接。(5)速算也是计算,是将硬算化为巧算。(6)能提高计算的速度及能力,并能培养严谨细致、灵活巧妙的工作习惯。
