a) 6/11 : 3/11 = 2
b) 14/5 : 7/10 = 4
c) 3 : 7/4 = 12/7
d) 24 : 48/9 = 9/2
a) \(\dfrac{6}{11}\div\dfrac{3}{11}=\dfrac{6}{11}\times\dfrac{11}{3}=\dfrac{66}{33}=2\)
b) \(\dfrac{14}{5}\div\dfrac{7}{10}=\dfrac{14}{5}\times\dfrac{10}{7}=\dfrac{140}{35}=4\)
c) \(3\div\dfrac{7}{4}=3\times\dfrac{4}{7}=\dfrac{12}{7}\)
d) \(24\div\dfrac{48}{9}=24\times\dfrac{9}{48}=\dfrac{216}{48}=\dfrac{9}{2}\)
