Question

Вычислите: а) 4 3/4+1/6,б) 5-3 4/7,в) -4*3 4/15,г) 3 3/7:(-16),д) -4 5/11-3 7/11

Answer 1

$4 \frac{3}{4} + \frac{1}{6} =4 \frac{9}{12} + \frac{2}{12} =4 \frac{11}{12} \\ \\ 5-3 \frac{4}{7} =4 \frac{7}{7} -3 \frac{4}{7} =1 \frac{3}{7} \\ \\ -4*3 \frac{4}{15} =-12 \frac{16}{15} =-13 \frac{1}{15} \\ \\ 3 \frac{3}{7} :(-16)= \frac{24}{7} *(- \frac{1}{16} )=- \frac{3}{14}$ 

$-4 \frac{5}{11} -3 \frac{7}{11} =-(4 \frac{5}{11} +3 \frac{7}{11} )=-7 \frac{12}{11}=-8 \frac{1}{11}$
