Answer 1

Dễ mà ta

11/9

3/175

Answer 2

15/18 + 7/18 = 22/18 = 11/9

11/10 - 3/5 x 7/5 = 11/10- 21/25 = 13/50

Answer 3

\(=\dfrac{15}{18}+\dfrac{7}{18}=\dfrac{22}{18}=\dfrac{11}{9}\\ =\dfrac{11}{10}-\dfrac{3}{5}\times\dfrac{7}{5}=\dfrac{11}{10}-\dfrac{21}{25}=\dfrac{13}{50}\)

Answer 4

5/6 + 7/18= 15/18 + 7/18= 22/18=11/9

11/10 - 3/5 x 7/5 = 11/10 - 21/25 = 13/50

Answer 5

5/6 + 7/18 = 15/18 + 7/18 = 22/18

11/10 - 3/5 : 5/7 = 11/10 - 3/5 x 7/5 = 11/10 - 21/25 = 55/50 - 42/50 = 13/50

Answer 6

5/6+ 7/18= 11/ 9

11/10- 3/5: 5/7= 13/ 50
