Answer 1

\(a,-Đ\\ b,-S\\ 4\dfrac{1}{3}:3\dfrac{1}{4}=\dfrac{4}{3}\\ \)

\(c,-S\\ 5\dfrac{1}{6}\times3=\dfrac{31}{2}\\ d,-Đ\)

Answer 2

`a)2 3/5 xx 3 1/3 = 13/5 xx 10/3= 130/15= 8 2/3 (Đ)`

`b, 4 1/3 : 3 1/4= 13/3 : 13/4= 13/3 xx 4/13=1 1/3(S)`

`c)5 1/6 xx 3= 31/6 xx 3= 15 1/2 (S)`

`d) 6 : 2 2/3= 6 : 8/3= 6 xx 3/8= 18/8=9/4(Đ)`
