По действиям

Answer 1

$1)2 \frac{2}{3} \times 2 \frac{1}{7} = \frac{8 \times 15}{3 \times 7} = \frac{40}{7} = 5 \frac{5}{7} \\ 2)9 - 5 \frac{5}{7} = 8 \frac{7}{7} - 5 \frac{5}{7} = 3 \frac{2}{7} \\ 3)3 \frac{2}{7} \times \frac{21}{46} = \frac{23 \times 21}{7 \times 46} = \frac{3}{2} = 1 \frac{1}{2}$
