Question

Вычислите:
$( 8frac{7}{12} -2 frac{17}{36}) * 2,7- 4 frac{1}{3} : 0,65$

Answer 1

$8 frac{21}{36}-2 frac{17}{36}=6 frac{4}{36}=6 frac{1}{9} \ \ 6 frac{1}{9} * 2 frac{7}{10} = frac{55}{9}* frac{27}{10}= frac{33}{2} \ \ frac{13}{3}: frac{65}{100}= frac{13}{3} * frac{100}{65} = frac{20}{3} \ \ frac{33}{2} - frac{20}{3} = frac{99-40}{6}= frac{59}{6}=9 frac{5}{6}$
