Question

数学题目很简单
3/26x（1/4 + 5/6）
=
14/9 x 7/23 x 9/14
=
1/25 x 7/18 x 75
=
1/3 x 2/5 x 3
=
4/7 x 5/13 x 14
=
5/8 x 7/9 x 3/7
=
16 x 1/3 x 9
=
(5/8 x 3/7）x 8/5
=
2/3 x 14 x 5/7
=
24 x(3/8-1/3)
=

5/13-5/13 x 5/18
=
67 x 23/66
=
14/15 x (1/2-3/7)
=
要简算的哦!
满意的话加100
写清楚点

Answer 1

3/26x（1/4 + 5/6）
=3/26*(3+10)/6
=3/26*13/6
=1/4
14/9 x 7/23 x 9/14
=14/9*9/14*7/23
=1*7/23
=7/23
1/25 x 7/18 x 75
= 1/25*75* 7/18
=3* 7/18
=7/6
1/3 x 2/5 x 3
=1/3*3*2/5
=1*2/5
=2/5
4/7 x 5/13 x 14
=4/7*14*5/13
=8*5/13
=40/13
5/8 x 7/9 x 3/7
=5/8*1/3
=5/24
16 x 1/3 x 9
=16*3
=48
(5/8 x 3/7）x 8/5
=5/8*8/5*3/7
=1*3/7
=3/7
2/3 x 14 x 5/7
=
24 x(3/8-1/3)
=24*3/8-24*1/3
=9-8
=1

5/13-5/13 x 5/18
=5/13(1-5/18)
=5/13*13/18
=5/18
67 x 23/66
=(66+1)*23/66
=66*23/66+1*23/66
=23+23/66
=23又23/66
14/15 x (1/2-3/7)
=14/15*1/2-14/15*3/7
=7/15-2/5
=（7-6）/15
=1/15
