Bài 2. a, Các phân số được sắp xếp theo thứ tự từ bé đế lớn là:
A, 2/3; 5/6; 4/2 B, 5/6; 4/2; 2/3 C, 4/2; 5/6; 2/3 D, 2/3; 4/2; 5/6.
b, Các phân số được sắp xếp theo thứ tự từ lớn đến bé là:
A, 2/3; 5/6; 4/2 B, 5/6; 4/2; 2/3 C, 4/2; 5/6; 2/3 D, 2/3; 4/2; 5/6.
6/2×4 + 6/4×6 + 6/6×8 + ...+ 6/20×20
a)34/7-4
b)25/4-3
c)6/18-6/24
d)5/6+(5/9-1/4)
các phân số được viết theo thứ tự từ bé đến lớn là :
a . 5/6, 3/8 , 3/8,3/4 , 8/6 b 5/6 , 3/4 , 8/6, 3/8
c . 3/8, 3/4, 8/6, 5 /6 d 3/8 , 3/4, 5/6,8/6
tính giá trị biểu thức: a) 6 : 5/2 - 3/10 b) 4/6 :4/3 + 4/3 c) 5/2 x 1/3 + 1/4 d) 6/7 : (1/2 x 3/4 ) -5/8
8/2 + 8/4 + 8/6 + 6/4 + 6/2 + 4/2
ai trả lời đầu tiên mình ticks nhé
tính bằng cách thuận tiện nhất:
( 2/3 x 4/5) x 5/6 (4/5 + 5/4) x 3/4 27/12 + 17/6 - 25/36 - 15/6
