. Bài 3: Các phân số được xếp theo thứ tự lớn dần là: a. 1/2 ; 1/3 ; 3/8 ; 5/12
b. 1/3 ; 1/2; 5/12; 3/8
c. 1/3 ; 3/8 ; 5/12 ; 1/2
d. 3/8 ; 1/3 ; 1/2 ; 5/12
1) Tính
a) 9/12 - 5/12 ; 9/12 - 1/3 ; 7 - 3/2 ; 9/4 - 2
b) 2/7 + 5/7 ; 1/3 + 5/12 ; 2 + 2/5 ; 6/9 + 3
c) 2/3 x 4/7 ; 3/11 x 2 ; 4 x 2/7
d) 8/21 : 4/7 ; 8/7 : 4 ; 5 : 2/3

5/3 - 3/5 + 6/11 3/5 x 3/7 : 5
đúng ghi Đ sai ghi S
a,5/9+2/3=7/12 b,5/9+2/3=7/27
c, 5/9+2/3=11/9 d, 5/9+2/3=10/12
5/12 +5/6 -3/4
1 - ( 1/5 +1/2 )
3/5 + 6/4 + 5/2
7/8 * 3+ 5/12
X x 2 và 2/3 = 3 và 4/8 + 6 và 5/12
1-x = 2 và 5/12 : 3 và 5/9
3 và 7/8 x X - 2 và 3/4 = 3 và 6/12 x 10/8 - 1/3
điền Đ hay S
a) 3/4+5/12 =7/6
b) 6/11 nhân 22/9 =2/3
c) 5/12 : 3/4= 5/9
d) 5/2 - 4/5 nhân 3/8= 5/9
