Answer 2

спасибо тебе огромное)

Answer 3

$1 frac{1}{3} - frac{3}{4} *( frac{5}{12} - frac{1}{3} )= 1 frac{1}{3} - frac{3}{4} * frac{5}{12} +frac{3}{4} * frac{1}{3} =1 frac{1}{3} - frac{1}{4} * frac{5}{4} +frac{1}{4} * frac{1}{1} =$$1 frac{16}{48} - frac{15}{48} +frac{12}{48} =1frac{1}{48} +frac{12}{48}=1frac{13}{48}$
