Answer 1

$5 \frac{4}{7} -(2.5+1 \frac{1}{3} ): \frac{1}{3} = -5 \frac{13}{14} \\ \\ 1)2 \frac{1}{2} +1 \frac{1}{3} =2 \frac{3}{6} +1 \frac{2}{6} =3 \frac{5}{6} = \frac{23}{6} \\ \\ 2) \frac{23}{6} *3= \frac{23}{2} =11 \frac{1}{2} \\ \\ 3)5 \frac{4}{7} -11 \frac{1}{2} =5 \frac{8}{14} -11 \frac{7}{14} =5 \frac{8}{14} -10 \frac{21}{14} =-5 \frac{13}{14}$
