\(2+\dfrac{2}{3}=\dfrac{6}{3}+\dfrac{2}{3}=\dfrac{8}{3}\)
2 + \(\dfrac{2}{3}\) = \(\dfrac{8}{3}\)

Các phân số 1/3: 1/6: 5/2: 3/2 xếp theo thứ tự tăng dần
a. 1/3; 1/6; 5/2; 3/2 b. 1/3; 5/2; 1/6; 3/2 c. 1/6; 1/3; 3/2; 5/2 d. 1/6; 3/2; 3/2; 5/2
a) = ……………………………3/7 x 4/5………………………… | 2/5 + 3/4 ………………………..……….…..…………………… |
b) =……2/5 : 4……………………………………….…………… | ……1/4 + 2………………….……….………………………… |
c) =…2/5 : 2/3……………………………………..…………..… | 2/3 - 38…………………………………………………………… |
d) 5 - 2/3………………………………………..…..………… | 2/5 x 3………………………………………………………… |
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.
cách làm bài 3/2+5/3=, 2/3:5, 9/2-2/3, 3/2 nhân 5/3
2/3+5/2-3/4=
2/5*1/2/1/3=
2/9/2/9/1/2=
4/5-1/2+1/3=
1/2*1/3+1/4=
2/7/2/3-1/7=
2/3+5/2-3/4=
4/5-1/2+1/3=
2/5×1/2:1/3=
1/2×1/3+1/4=
2/9:2/9×1/2=
2/7:2/3-1/7=
a)2/5 + 3/4 e) 1/4+2
b)2/3 - 3/8 g)2/5 nhân 3
c)3/7 nhân 4/5 f)2/5:4
d)2/5:2/3 5-2/3
làm bước trung gian cho mình luôn nhé
d)2/5 : 2/3
c)3/7 nhân 4/5
d)2/5 : 2/3
2)tính :
a)2/5*1/2:1/3;b)2/9:2/3*1/3;c)1/2*1/3+1/4;d)2/7:2/3-1/7
