Answer 2

Step-by-step explanation:

$1) \frac{2}{5} \times 5 \frac{1}{4} = \frac{2}{5} \times \frac{21}{4} = \frac{42}{20} = \frac{21}{10} \\ \\ 2)6 \frac{2}{5} \times \frac{7}{9} = \frac{32}{5} \times \frac{7}{9} = \frac{224}{45 } \\ \\ 3) \frac{3}{2} \times 5 \frac{1}{3} = \frac{3}{2} \times \frac{16}{3} = 8 \\ \\ 4) \frac{5}{6} \times 2 \frac{3}{7} = \frac{5}{6} \times \frac{17}{7} = \frac{85}{42} \\ \\5) \: 3 \frac{2}{5} \times \frac{4}{7} = \frac{17}{5} \times \frac{4}{7} = \frac{68}{35} \\ \\ 6) \: 2 \frac{3}{5} \times 3 = \frac{13}{5} \times 3 = \frac{39}{5} \\ \\ 7) \: 3 \frac{4}{7} \times \frac{3}{5} = \frac{25}{7} \times \frac{3}{5} = \frac{15}{7}$
