An easy way to order them would be to convert them into fractions with the same denominator:
[tex]0.1=\frac{1}{10}=\frac{10}{100}[/tex][tex]\frac{1}{2}=\frac{50}{100}[/tex][tex]\frac{10}{11}=\frac{90}{99}[/tex][tex]\frac{51}{100}[/tex][tex]\frac{24}{50}=\frac{48}{100}[/tex][tex]\frac{3}{20}=\frac{15}{100}[/tex]From least to greatest:
[tex]0.1,\frac{3}{20},\frac{24}{50},\frac{1}{2},\frac{51}{100},\frac{10}{11}[/tex]
