能简算的要简算,写过程.非常急,12:40以前要用
(1)3/11÷(3/4×3/11)
(2)6/5×2/3÷2/7÷8/7
(3)5/9×3/5×9/2
(4)3/7×(1÷2/3)

能简算的要简算,写过程.非常急,12:40以前要用(1)3/11÷(3/4×3/11)(2)6/5×2/3÷2/7÷8/7(3)5/9×3/5×9/2(4)3/7×(1÷2/3)(5)5/8×4×1/5(6)12÷(3/4÷1/5)(7)7/13÷9+1/9×6/13(8)32-4/3-8/3(9
以下省略了原式
(1)=11/3÷3/4÷3/11
= 3/11÷3/11÷3/4
= 4/3
(2)=1/5×1/1×1/7×4/7(约分)
=49/20
(3) =1/1× 3/1× 1/2(约分)
=3/2
(4)=3/7× 1× 2/3(3和3约分)
=1/7× 1× 2/1
=2/7
(5)=(8和4约分得2) (5和5约分得1)
=1/2
(6)=12÷3/4× 1/5
=12×4/3×1/5
= 16/5
(7) =7/13×1/9+1/9×6/13
=(7/13+6/13)×1/9
=1/9
(8)=32-(4/3+8/3)
=32-4
=28
(9)=1/6×6
=1
(10)=(51+17/5)×1/17
= 51×1/17 + 17/5×1/17
=3又1/5
(11)=1/2×(5/12+1/3)
= 1/2 × 3/4
=3/8
(12)=1/4×3/7+1/4×4/7+1/4×1
=1/4×(3/7+4/7+1)
= 1/2
(13)=3/4×(2/3+1/3)
=3/4×1
=3/4
(14)=120×1/2+ 120×1/3+120×1/4
=60+40+30
=130
以上答案绝对准确 我们刚校对的 很辛苦的 再施舍点分也行
4/3,245/144,3/2,9/14,1/2,16/5,1/9,28,5.108/85,11/24,1/2,3/4,130
