bài 1:
1/4 + 2/3 2/7 + 2/3 2/5 + 1/3 2/3 + 1/2 1/3 + 3/5 4/5 + 1/3
1/8 + 3/4 1/36 + 5/12 1/3 + 1/6 + 1/18.
bài 2:
15/16 - 3/16 17/18 - 5/6 3/4 - 4/9 1/2 - 2/5 5/6 - 3/10 3-1/3
4/5 - 1/10 5/2 - 1 5/8 - 2/5.
Đúng ghi Đ, sai ghi S
5/6 - ( 7/12-1/4 ) =1/2
11/6 - ( 1/2 + 1/24 ) =3/9
19/24 -2/8 = 5/2
8/9 - 1/3 - 5/18 = 5/18 cảm ơn
Giúp mình với mình tick hết
7/6+5/12-1/18-1=? 13/6+5/18+3-7/12=?
3+11/4-1/12-3/16=? 2/5x7/4-2/5x3/4=?
1/8 + 3/4 1/36 + 5/12 1/3 + 1/6 + 1/18
1/3+1/6+1/18=
1/6+1/3+1/2+1/18
