sorry vì hơi dài giúp mik với
3/4 x ( 5/6 + 7/8)
B)1/11 : (6/7 - 5/6) - 20/11
D) (4 - 2/7 x3) : 1/3
bài 1:
a,1/10*2/9*3/8*4/7*5/6*6/5*7/4*8/3*9/2
b,8/11+4/17-5/11-3/17-65/9-8/17-3/17-6/17
đầy đủ nhé mn, trả lời đủ em tick
a, 4/11 + 6/11 b, 28/8 x 12/6 c, 7/4 - 5/8 d, 3/5 : 3/7
1/2+2/3+3/4+4/5+5/6+6/7+7/8+8/9+9/10+10/11+11/12+12/13+13/14+14/15=?
tinh bang hai cach
(6/11+5/11) * 3/7
(6/7-4/7) : 2/5
3/5 * 7/9 - 3/5 *2/9
8/15 : 2/11 + 7/15 :2/11
10/3...1/3. 10/6...3/8. 17/4...5/6. 1/3...5/9 5/8...7/5 3/4...15/6 10/9...10/11 7/8...7/2 15/9...3/8 15/7...15/8 16/5...16/7 25/11...1
{ < , >, = }
5/6......11/12 4/7.......3/4 5/8..........3/8
10/14.....5/7 10/9 .......10/11 8/15...........8/9
a)3/2 x 4/7 8/21 : 2/3 8/21 : 4/7 4/7 x 2/3
b)3/11 x 2 6/11 : 3/11 6/11 : 2 2 x 3/11
