$frac{24}{59} times ( frac{1}{2} + frac{7}{12} ) - frac{8}{9} times frac{10}{21}$

решаем по действиям :

$1) frac{1}{2} + frac{7}{12} = frac{6}{12} + frac{7}{12} = frac{13}{12} = 1 frac{1}{12}$

$2) frac{8}{9} times frac{10}{21} = frac{80}{189}$

$3) frac{24}{59} times 1 frac{1}{12} = frac{24}{59} times frac{13}{12} = frac{312}{708} = frac{26}{59}$

$4) frac{26}{59} - frac{80}{189} = frac{4914}{11151} - frac{4720}{11151} = frac{194}{11151}$
