Question

(33/14×14/3+12:9/4-60/4):(79/18-23/9). Это тема деление дробей

Answer 1

$1) \frac{33}{14} \times \frac{14}{3} = 11 \\ 2)12 \div \frac{9}{4} = \frac{12 \times 4}{9} = \frac{16}{3} = 5 \frac{1}{3} \\ 3) \frac{60}{4} = 15 \\ 4)11 + 5 \frac{1}{3} = 16 \frac{1}{3} \\ 5)16 \frac{1}{3} - 15 = 1 \frac{1}{3} \\ 6) \frac{79}{18} - \frac{23}{9} = \frac{79 - 46}{18} = \frac{33}{18} = \frac{11}{6} = 1 \frac{5}{6} \\ 7)1 \frac{1}{3} \div 1 \frac{5}{6} = \frac{4}{3} \div \frac{11}{6} = \frac{4 \times 6}{3 \times 11} = \frac{8}{11}$
