помогите. аожалуста!!!

Answer 1

$= frac{19}{12} :( frac{9}{24} + frac{10}{24} )= frac{19}{12} : frac{19}{24} = frac{19}{12} * frac{24}{19} =2$

------------------------------------------------------------------------
$= frac{17}{36} :( frac{21}{36} - frac{20}{36} )= frac{17}{36} : frac{1}{36} = frac{17}{36} * frac{36}{1} =17$

=19/12:(9/24+10/24)=19/12:19/24=19/12*24/19=2

--------------------------------------------------------------------------------
=17/36:(21/36-20/36)=17/36:1/36=17/36*36/1=17
