Answer 1

1)

$\frac{3}{4} \times \frac{6}{5} = \frac{9}{10}$

2)

$\frac{21}{5} \times \frac{3}{7} = \frac{9}{5} = 1 \frac{4}{5}$

3)

$\frac{3}{5} \times \frac{25}{4} = \frac{15}{4} = 3 \frac{3}{4}$

4)

$\frac{9}{5} \times \frac{2}{3} = \frac{6}{5} = 1 \frac{1}{5}$

5)

$\frac{5}{3} \times \frac{9}{2} = \frac{15}{2} = 7 \frac{1}{2}$

6)

$\frac{7}{5} \times \frac{12}{35} = \frac{12}{25}$

7)

$\frac{12}{5} \div \frac{15}{2} = \frac{12}{5} \times \frac{2}{15} = \frac{8}{25}$

8)

$\frac{6}{5} \div \frac{4}{11} = \frac{6}{5} \times \frac{11}{4} = \frac{33}{10} = 3 \frac{3}{10}$

9)

$\frac{3}{5} \div \frac{4}{35} = \frac{3}{5} \times \frac{35}{4} = \frac{21}{4} = 5 \frac{1}{4}$

10)

$\frac{15}{4} \div \frac{3}{7} = \frac{15}{4} \times \frac{7}{3} = \frac{35}{4} = 8 \frac{3}{4}$

11)

$\frac{21}{2} \div \frac{3}{5} = \frac{21}{2} \times \frac{5}{3} = \frac{35}{2} = 17 \frac{1}{2}$

12)

$\frac{14}{5} \div \frac{7}{2} = \frac{14}{5} \times \frac{2}{7} = \frac{4}{5}$
