五年級下冊脫式計算題及答案

2樓:小露解說

一、5.4÷1.8+240×1.5

=3+360

=363

二、9000÷72×(1.25×0.7×8)=9000÷72×7

=125×7

=875

三、61-(1.25+2.5×0.7)

=61-3

=58四、[(10-0.8)+9.85]-2÷0.125=19.05-2÷0.125

=19.05-16

=3.05

1、脫式計算,即遞等式計算,需將一系列的數字逐步計算。在脫式計算中要先算乘、除法,後算加、減法。在乘除法連繼計算時中,要按從左往右的順序依次計算,在四則運算中,加法和減法叫做第一級運算,乘法和除法叫做第二級運算。

4)÷5

=(31.8+12.8)÷5

=44.6÷5

=8,92,

31.5×4÷(6+3)

=31.5×4÷9

=126÷9

5樓:獨孤嶽麓

1、0.2008+2.008+20.08+200.8+2008

=0.2008×

(1+10+100+1000+10000)

=0.2008×11110

=2230.888

2、1÷(2÷3)÷(3÷4)÷(4÷5)÷(5÷6)÷……÷(2007÷2008)=1×3/2×4/3×5/4×6/5×……×2008/2007

=2008

3、1+1/3+1/6+1/10+……+1/2009×1004

=2×(1/2+1/6+1/12+1/20+……+1/2008×2009)

=2×(1-1/2+1/2-1/3+1/3-1/4+……+1/2008-1/2009)

=2×(1-1/2009)

=2×2008/2009

=4016/2009

4、2006個2006乘2007個2007再乘2008個2008的積的個位數是?

2006個2006的個位數字是6

2007個2007的個位數字是3

2008個2008的個位數字是6

6×3×6=108

所以2006個2006乘2007個2007再乘2008個2008的積的個位數字是8

5、325.24+425.24+625.24+925.24+525.24

=(300+400+600+900+500)+25.24×5

=2700+126.2

=2826.2

6、1/1×4+1/4×7+1/7×10+1/10×13+……+1/2005×2008

=(1-1/4+1/4-1/7+1/7-1/10+1/10-1/13+……+1/2005-1/2008)÷3

=(1-1/2008)÷3

=2007/2008÷3

=669/2008
