(1)1.25*17.6+36.1/0.8+2.36*12.5
1.25*17.6+36.1/0.8+2.36*12.5
=(5/4)*17.6+36.1*(5/4)+23.6*(50/4)
=176/8+361/8+236/8
=773/8=96.625
(2)7.5*2.3+1.9*2.5
7.5*2.3+1.9*2.5
=7.5*(1.9+0.4)+1.9*2.5
=(7.5+2.5)*1.9+7.5*0.4
=19+3 =22
(3)2004/2003*2005
2004/2003*2005
=(2004/2003)*(2003+2)
=2004+4008/2003
(4)276*543-267/276+543*275
276*543-267/276+543*275
=543*(276+275)-267/276
=543*551-267/276
1)五十二又二十五分之十一×79.45+159×47.56+七十九又二十分之十一×52.44
=52.44×79.45+159×47.56+79.55×52.44
=52.44×(79.45+79.55)+159×47.56
=52.44×159+159×47.56
=159×(52.44+47.56)
=159×100
=15900
3)2002+2001-2000-1999+1998+1997-1996-1995+……+2+1
=(2002-2000)+(2001-1999)+(1998-1996)+(1997-1995)+……+(6-4)+(5-3)+2+1
=2+2+2+2+……+2+2(从3-2002共2000个数,所以有1000个2)+2+1
=1000×2+2+1
=2003
4,5两题均用到一个转换式1/(A×B)=1/(B-A)×(1/A-1/B)
如1/15=1/(3×5)=1/(5-3)×(1/3-1/5)=1/2×(2/15)=1/15可验证一下
4)(1×2分之一)+(2×3分之一)+(3×4分之一)+……+(10×11分之一)
=1/(1×2)+1/(2×3)+1/(3×4)+……+1/(10×11)
=(1-1/2)+(1/2 - 1/3)+(1/3 - 1/4)+……+(1/10 - 1/11)
=1-1/11
=10/11
5)三分之一+十五分之一+三十五分之一+六十三分之一+九十九分之一
=1/(1×3)+1/(3×5)+1/(5×7)+1/(7×9)+1/(9×11)
=1/2×(1-1/3)+1/2×(1/3-1/5)+1/2×(1/5-1/7)+1/2×(1/7-1/9)+1/2×(1/9-1/11)
=1/2×(1 - 1/3 + 1/3 - 1/5 + 1/5 - 1/7 + 1/7 - 1/9 + 1/9 - 1/11)
=1/2×(1-1/11)
=1/2×10/11
=5/11
6)一又二分之一-六分之五+十二分之七-二十分之九+三十分之十一-四十二分之十三+五十六分之十五
(根据提示,1又1/2=1+1/2,+1/2+1/3=5/6……)
=(1+1/2)-(1/2+1/3)+(1/3+1/4)-(1/4+1/5)+(1/5+1/6)-(1/6+1/7)+(1/7+1/8)
=1+ 1/2 - 1/2 - 1/3 + 1/3 + 1/4 - 1/4 - 1/5 + 1/5 + 1/6 - 1/6 - 1/7 + 1/7 + 1/8
=1+1/8
=9/8
仔细看一下,不会很难,都可以简便算的。你自己看一下,有些题目化成分数会好算些,我不是六年级的,不知道你们学的和我们是否一样,只能找一些,抱歉,请原谅。

x=10/9×6/35
x=4/21
这个都不难,无非是通分后,相乘。
看下第二个,要求相同的数提出来,
(11/19)*10/(/11/19)*10
=[(11/19)/(11/19)]*10*11
=1*10*11
=110
主要是先观察,利用乘除法交换律,将相同相乘或相除,相比可以快点。

如今中小学生的作业越来越难,家长们对于这些题也愈发力不从心。即便只是六年级数学,就已经开始呈现出复杂性,所以家段逗长们偶尔做不出来,也情有可原。当然,孩子是家长不可推卸的责任,所以提前轿弊做好准备,也不失为一种 *** 。那么,六年级简便运算100道带答案有哪些题目?简便计算题六年级带答案的题要用到哪些定律?
六年级简便运算100道带答案
0.4×125×25×0.8
=(0.4×25)×(125×0.8)
=10×100=1000
1.25×(8+10)
=1.25×8+1.25×10
=10+12.5=22.5
9123-(123+8.8)
=9123-123-8.8
=9000-8.8
=8991.2
1.24×8.3+8.3×1.76
=8.3×(1.24+1.76)
=8.3×3=24.9
9999×1001
=9999×(1000+1)
=9999×1000+9999×1
=10008999
14.8×6.3-6.3×6.5+8.3×3.7
=(14.8-6.5)×6.3+8.3×3.7

简便计算题六年级带答案
1、24.6-3.98+5.4-6.02
解析:此题利用加法结合律,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(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,先利用凑闭燃族整法把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 *** ,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
