Question

1 3/35:1 1/56-3 5/21:1 22/63 помогите пожалуйста

Answer 1

$1 frac{3}{35} div 1 frac{1}{56} = frac{38}{35} div frac{57}{56} = \ frac{38}{35} times frac{56}{57} = frac{2times 8}{5 times 3} = frac{16}{15} = 1 frac{1}{15}$
$3 frac{5}{21} div frac{22}{63 } = frac{68}{21} div frac{22}{63} = \ = frac{68}{21} times frac{63}{22} = frac{34 times 3}{11} = frac{102}{11} =$
$9 frac{3}{11}$
$1 frac{1}{15} - 9 frac{3}{11} = 1 frac{11}{165} - 9 frac{45}{165} = \ = - 8 frac{34}{165}$
