Question

сократите дроби 21/56, 144/120, 156/128, 396/240.

Answer 1

$displaystylefrac{21}{56}=frac{3*7}{8 * 7} =frac{3}{8}$

$displaystylefrac{144}{120} =1frac{24}{120} =1frac{24}{24*5} =1frac{1}{5}$

$displaystylefrac{156}{128}=1frac{28}{128}=1frac{4*7}{4*32}=1frac{7}{32}$

$displaystylefrac{396}{240}=1frac{156}{240}=1frac{12*13}{12*20}=1frac{13}{20}$
