Question

11/20 và 6/8 ; 20/50 và 1/5

Answer 1

\(\dfrac{11}{20};\dfrac{6}{8}=\dfrac{3}{4}=\dfrac{3\times5}{4\times5}=\dfrac{15}{20}\)

Vì \(\dfrac{11}{20}< \dfrac{15}{20}\rightarrow\dfrac{11}{20}< \dfrac{6}{8}\)

\(\dfrac{20}{50}=\dfrac{2}{5};\dfrac{1}{5}\)

Vì \(\dfrac{2}{5}>\dfrac{1}{5}\rightarrow\dfrac{20}{50}>\dfrac{1}{5}\)

Answer 2

11/20<15/20→11/20<6/8

2/5>1/5=>20/50>1/5

Answer 3

11/20<15/20

20/50>1/5
