Answer 1

1)

$2 \frac{1}{3} \times 1 \frac{1}{5} = \frac{7}{3} \times \frac{6}{5} = \frac{14}{5} = 2.8$

2)

$2 \frac{7}{9} \times 3 \frac{3}{5} = \frac{25}{9} \times \frac{18}{5} = 10$

3)

$2 \frac{1}{2} \times 1 \frac{3}{5} = \frac{5}{2} \times \frac{8}{5} = 4$

4)

$3 \frac{7}{9} \times 1 \frac{1}{17} = \frac{34}{9} \times \frac{18}{17} = 4$

5)

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

6)

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

7)

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

8)

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