Question

so sanh cac phan so 35/56,35/58,24/54

Answer 1

\(\dfrac{35}{56}\) và \(\dfrac{35}{58}\)

\(\Rightarrow\dfrac{35}{56}>\dfrac{35}{58}\)

\(\dfrac{24}{54}=\dfrac{4}{9}\) và \(\dfrac{35}{56}=\dfrac{5}{8}\)

Quy đồng: 

\(\dfrac{4}{9}=\dfrac{32}{72};\dfrac{5}{8}=\dfrac{45}{72}\Rightarrow\dfrac{4}{9}< \dfrac{5}{8}\)

Vậy: \(\dfrac{35}{56}\) lớn nhất 

So sánh \(\dfrac{4}{9}=\dfrac{232}{522};\dfrac{35}{58}=\dfrac{315}{522}\Rightarrow\dfrac{35}{58}>\dfrac{24}{54}\)

Vậy ta có: \(\dfrac{35}{56}>\dfrac{35}{58}>\dfrac{24}{54}\)
