Sagot :
Well, [tex]\frac{2}{10}=\frac{1}{5}=\frac{3}{15}=\frac{4}{20}=\frac{5}{25}=\frac{n}{5n}[/tex] for every n integer.
[tex]\frac{3}{11}=\frac{6}{22}=\frac{9}{33}=\frac{12}{44}=\frac{15}{55}=\frac{3n}{11n}[/tex] for every n integer.
[tex]\frac{1}{12}=\frac{2}{24}=\frac{3}{36}=\frac{4}{48}=\frac{5}{60}=\frac{n}{12n}[/tex] for every n integer.

2/10 is equal to 1/5 cause u divide by 2 and 4/20 cause u divide by 2.for 3/11 r 6/22 cause multiply by 2 and 9/33 cause u multiply by3 finally 1/12 r 2/24 cause u multiply by 2 and 3/36 cause u multiply by 3
