Answer 2

$1)2 \frac{1}{4} \times 1\frac{1}{3} = \frac{9}{4} \times \frac{4}{3} = 3 \\ 2)5 \frac{5}{12} \times 1 \frac{5}{13} = \frac{65}{12 } \times \frac{18}{13} = \frac{5}{2} \times 3 = \frac{15}{2} = 7 \frac{1}{2} \\ 3)4 \frac{3}{8} \times 1 \frac{1}{7} = \frac{35}{8} \times \frac{8}{7} = 5 \\ 4)4 \frac{9}{10} \times 3 \frac{1}{3} = \frac{49}{10} \times \frac{10}{3} = 49 \times \frac{1}{3} = \frac{49}{3} = 16 \frac{1}{3}$
