Explanation:
1.
[tex] \frac{7}{12} \div \frac{7}{10} = \frac{7}{12 } \times \frac{10}{7} = \frac{5}{6} \\ [/tex]
2.
[tex] \frac{1}{3} \div \frac{1}{6} = \frac{1}{3} \times \frac{6}{1} = 2 \\ [/tex]
3.
[tex]1 \frac{1}{2} \div 1 \frac{1}{2} = \frac{3}{2} \times \frac{2}{3} = 1 \\ [/tex]
4.
[tex]2 \frac{1}{4} \div 2 \frac{3}{4} = \frac{9}{4} \times \frac{4}{11} = \frac{9}{11} \\ [/tex]
5.
[tex] \frac{2}{3} \div 2 \frac{1}{2} = \frac{2}{3} \times \frac{2}{5} = \frac{4}{15} \\ [/tex]
