Câu 9 :Tính bằng cách thận tiện
26 x 8 + 4 x 13 - 10 x 26
7/17 + 6/5 x 7/12 =
9/8 - 7/13 + 14/26 =
8/15 - 2/9 + 4/7 =
Tính : [PHÂN SỐ]
14 x 9 / 21 x 3.
15 x 26 x 8/45 x 13 x 16
Tính :
2/5 + 11/15 =
7/8 - 7/9 =
11/13 x 26/31 =
16/24 : 4 =
30 : 6/5 =
9/16 : 4 =
1/2 : 1/3 x 8/15 =
tính
a) 1/3 + 3/4 x 2/9
b) 2-(2/5 +2/3)
c) 2/5 : 4/7 +1/3
d)9/13 : 3/26 - 8/13
