Question

Answer 1

\(a,7>5=>\dfrac{7}{12}>\dfrac{5}{12}\\ b,\dfrac{2}{5}=\dfrac{2.5}{25}=\dfrac{10}{25}\\ 10>7=>\dfrac{2}{5}>\dfrac{7}{25}\\ c,\dfrac{9}{11}=\dfrac{9.24}{264}=\dfrac{216}{264}\\ \dfrac{9}{24}=\dfrac{9.11}{264}=\dfrac{99}{264}\\ 216>99=>\dfrac{9}{11}>\dfrac{9}{24}\\ d,\dfrac{1212}{1313}=\dfrac{12}{13}=>\dfrac{12}{13}=\dfrac{1212}{1313}\\ e,\dfrac{4}{5}=\dfrac{4.9}{45}=\dfrac{36}{45}\\ \dfrac{10}{9}=\dfrac{10.5}{45}=\dfrac{50}{45}\\ 36< 45=>\dfrac{4}{5}< \dfrac{10}{9}\)
