Coin Hunter · Answer

$\dfrac{5}{11}:\dfrac{4}{17}=\dfrac{5}{11}\times\dfrac{17}{4}=\dfrac{85}{44}$

$3+\left(\dfrac{6}{25}:\dfrac{4}{15}\right)=3+\left(\dfrac{6}{25}\times\dfrac{4}{15}\right)=3+\dfrac{8}{125}=\dfrac{383}{125}$

$\dfrac{3}{12}:8=\dfrac{3}{12}\times\dfrac{1}{8}=\dfrac{3}{96}=\dfrac{1}{32}$

$16:\dfrac{4}{3}=16\times\dfrac{3}{4}=12$Câu trả lời: $\dfrac{5}{11}:\dfrac{4}{17}=\dfrac{5}{11}\times\dfrac{17}{4}=\dfrac{85}{44}$

$3+\left(\dfrac{6}{25}:\dfrac{4}{15}\right)=3+\left(\dfrac{6}{25}\times\dfrac{4}{15}\right)=3+\dfrac{8}{125}=\dfrac{383}{125}$

$\dfrac{3}{12}:8=\dfrac{3}{12}\times\dfrac{1}{8}=\dfrac{3}{96}=\dfrac{1}{32}$

$16:\dfrac{4}{3}=16\times\dfrac{3}{4}=12$
