Question

Tính B = \(\dfrac{4}{9}\)x\(\dfrac{1}{3}\)+\(\dfrac{4}{9}\)x\(\dfrac{2}{3}\)+\(\dfrac{14}{9}\)

Vậy B = ......(chú ý rút gọn về phân số tối giản, ví dụ 5/1 viết là 5)

Answer 1

B=4/9(1/3+2/3)+14/9=4/9+14/9=2/1

Answer 2

B = 2/1 = 2

Answer 3

B=4/9(1/3+2/3)+14/9

B=4/9+14/9

B=2/1

Answer 4

B = 4/9 x 1/3 + 4/9 x 2/3 + 14/9

B = 4/9 x ( 1/3 + 2/3) + 14/9

B = 4/9 x 1 + 14/9

B = 4/9 + 14/9

B = 18/9

B = 2

Answer 5

= 2

Answer 6

`B=4/9(1/3+2/3)+14/9`

`B=4/9+14/9`

`B=2/1`
