Answer 1

$\frac{20}{30} = \frac{10}{15} = \boxed{ \frac{2}{3} }$

$\frac{12}{20} = \frac{6}{10} = \boxed{ \frac{3}{5} }$

$\frac{14}{21} = \boxed{ \frac{2}{3} }$

$\frac{16}{40} = \frac{8}{20} = \frac{4}{10} = \boxed{ \frac{2}{5} }$

$\frac{15}{25} = \boxed{ \frac{3}{5} }$

$\frac{200}{45} = \boxed{ \frac{40}{9} }$

$\frac{28}{21} = \boxed{ \frac{4}{3} }$

$\frac{72}{40} = \frac{36}{20} = \frac{18}{10} = \boxed{ \frac{9}{5} }$

espero ter ajudado!!!!!!
