б) 2 5/6 - 1 5/12
В) 4 - 1 2/3
Г) 3 2/7 - 6/7
!!!!! СРОЧНО!!!!!

Answer 1

$3 frac{3}{4}+1 frac{1}{2}= frac{15}{4}+ frac{3}{2}= frac{15+6}{4}= frac{21}{4}=5 frac{1}{4}$

$2 frac{5}{6}-1 frac{5}{12}= frac{17}{6}- frac{17}{12}= frac{34-17}{12}= frac{17}{12}=1 frac{5}{12}$

$4-1 frac{2}{3}= frac{12}{3}- frac{5}{3}= frac{7}{3}=2 frac{1}{3}$

$3 frac{2}{7}- frac{6}{7}= frac{23}{7}- frac{6}{7}= frac{17}{7}=2 frac{3}{7}$
