b) 9/16 - 3/8 =

c) 11/10 + 3/5 : 2/3 =

các bạn trả lời hộ mình viết đầy đủ cách giải nha, đừng làm tắt, mik tặng 1 tim

Answer 1

`(a):(5)/(6)+(7)/(12)`

`=(10)/(12)+(7)/(12)`

`=(17)/(12)`

`(b):(9)/(16)-(3)/(8)`

`=(9)/(16)-(6)/(16)`

`=(3)/(16)`

`(c):(11)/(10)+(3)/(5):(2)/(3)`

`=(11)/(10)+(3)/(5)xx(3)/(2)`

`=(11)/(10)+(9)/(10)`

`=(20)/(10)=2`

Answer 2

a) \(\dfrac{5}{6}+\dfrac{7}{12}=\dfrac{10}{12}+\dfrac{7}{12}=\dfrac{10+7}{12}=\dfrac{17}{12}\)

b) \(\dfrac{9}{16}-\dfrac{3}{8}=\dfrac{9}{16}-\dfrac{6}{16}=\dfrac{9-6}{16}=\dfrac{3}{16}\)

c) \(\dfrac{11}{10}+\dfrac{3}{5}:\dfrac{2}{3}=\dfrac{11}{10}+\dfrac{3}{5}\cdot\dfrac{3}{2}=\dfrac{11}{10}+\dfrac{3\cdot3}{5\cdot2}=\dfrac{11}{10}+\dfrac{9}{10}=\dfrac{11+9}{10}=\dfrac{20}{10}=2\)
