Answer 1

$\tt\displaystyle\frac{6}{9}=\frac{2*3}{3*3}=\frac{2}{3}$

$\tt\displaystyle\frac{5}{15}=\frac{5*1}{5*3}=\frac{1}{3}$

$\tt\displaystyle\frac{12}{15}=\frac{4*3}{5*3}=\frac{4}{5}$

$\tt\displaystyle\frac{10}{35}=\frac{5*2}{5*7}=\frac{2}{7}$

$\tt\displaystyle\frac{18}{21}=\frac{6*3}{7*3}=\frac{6}{7}$

$\tt\displaystyle\frac{6}{18}=\frac{6*1}{6*3}=\frac{1}{3}$

$\tt\displaystyle\frac{30}{33}=\frac{3*10}{3*11}=\frac{10}{11}$

$\tt\displaystyle\frac{14}{49}=\frac{2*7}{7*7}=\frac{2}{7}$

$\tt\displaystyle\frac{24}{27}=\frac{3*8}{3*9}=\frac{8}{9}$

$\tt\displaystyle\frac{16}{40}=\frac{2*8}{5*8}=\frac{2}{5}$

$\tt\displaystyle\frac{36}{39}=\frac{3*12}{3*13}=\frac{12}{13}$

$\tt\displaystyle\frac{100}{200}=\frac{1*100}{2*100}=\frac{1}{2}$
