Step-by-step explanation:
1.
[tex] \frac{7}{8} \div \frac{3}{5} \\ \frac{7}{8} \times \frac{5}{3} \\ = \frac{35}{24} [/tex]
2.
[tex] \frac{17}{3} \div \frac{1}{7} \\ \frac{17}{7} \times \frac{7}{1} \\ = 17[/tex]
3.
[tex] \frac{3}{5} \div \frac{1}{2} \\ \frac{3}{5} \times \frac{2}{1} \\ = \frac{6}{5} [/tex]
4.
[tex] \frac{39}{4} \div \frac{3}{4} \\ \frac{39}{4} \times \frac{4}{3} \\ = \frac{39}{3} \\ = 13[/tex]
5.
[tex] \frac{3}{5} \div \frac{1}{5} \\ \frac{3}{5} \times \frac{5}{1} \\ = \frac{3}{1} \\ = 3[/tex]
6.
[tex] \frac{2}{5} \div \frac{8}{10} \\ \frac{2}{5} \times \frac{10}{8} \\ \frac{4}{1} \times \frac{2}{4} \\ = \frac{2}{1} \\ = 2[/tex]
7.
[tex]6 \div \frac{4}{3} \\ 6 \times \frac{3}{4} \\ 2 \times \frac{3}{2} \\ = \frac{6}{2} \\ = 3[/tex]
8.
[tex] \frac{7}{2} \div 2 \\ \frac{7}{2} \times \frac{1}{2} \\ = \frac{7}{4} [/tex]
9.
[tex]108 \div \frac{9}{4} \\ 108 \times \frac{4}{9} \\ 12 \times 4 \\ = 48[/tex]
10.
[tex]6 \div \frac{1}{8} \\ 6 \times 8 \\ = 48[/tex]
