Answer 1

$frac{12}{15}= frac{4}{5}$

$frac{21}{35} = frac{3}{5}$

$frac{12}{30} = frac{2}{5}$

$frac{45}{50} = frac{9}{10}$

$frac{18}{90} = frac{1}{5}$

$frac{56}{80} = frac{7}{10}$

$frac{9}{12} = frac{3}{4}$

$frac{21}{60} = frac{7}{20}$

$frac{54}{180} = frac{3}{10}$

$frac{102}{24} = frac{17}{4} = 4 frac{1}{4}$

$frac{135}{60}= frac{27}{12}=2 frac{1}{4}$

$frac{639}{300}= frac{213}{100}=2 frac{13}{100}$
