Question

ПОМОГИТЕ СРОЧНО! !!!!! (1 1/2 + 2 2/3+3 3/4):(14-15 1/8:2 1/5)*3 3/5 ДАМ КОРОНУ,ЗА ОТЛИЧНОЕ ПОЯСНЕНИЕ!

Answer 1

$1)1 \frac{1}{2} +2 \frac{2}{3} +3 \frac{3}{4} =1+2+3+ \frac{6+8+9}{12} =6 \frac{23}{12} \\ 2)15 \frac{1}{8} : 2 \frac{1}{5} = \frac{121}{8} : \frac{11}{5} = \frac{121}{8} * \frac{5}{11} = \frac{55}{8} =6 \frac{7}{8} \\ 3)14-6 \frac{7}{8} =7 \frac{1}{8} \\ 4)6 \frac{23}{12}:7 \frac{1}{8} = \frac{95}{12} : \frac{57}{8} = \frac{95}{12} * \frac{8}{57} = \frac{190}{171} = \frac{10}{9} \\ 5) \frac{10}{9} *3 \frac{3}{5} = \frac{10}{9} * \frac{18}{5} =4$
