1) 7 1/2×2 4/15
2)5 1/6×3 1/7
3)3 3/7×2 1/3
4)7 1/3×2 2/11

Answer 1

Пошаговое объяснение:

$7\frac{1}{2} \times 2 \frac{4}{15 } = \frac{15}{2} \times \frac{34}{15} = \frac{17}{1} = 17$

$5 \frac{1}{6} \times 3 \frac{1}{7} = \frac{31}{6} \times \frac{22}{7 } = \frac{31}{3} \times \frac{11}{7} = \frac{341}{21} = 16 \frac{5}{21}$

$3 \frac{3}{7} \times 2 \frac{1}{3} = \frac{24}{7} \times \frac{7}{3} = \frac{8}{1} = 8$

$7 \frac{1}{3} \times 2 \frac{2}{11} = \frac{22}{3} \times \frac{24}{11} = \frac{16}{1} = 16$
