[tex] \frac{7}{12} \times \frac{6}{7} = \frac{1}{2} [/tex]
[tex]1 \frac{2}{3} \times 5 = \frac{5}{3} \times 5 = \frac{25}{3} = 8 \frac{1}{3} [/tex]
[tex]2 \frac{1}{5} \times 1 \frac{2}{11 } = \frac{11}{5} \times \frac{23}{11} = \frac{23}{5} = 4 \frac{3}{5} [/tex]
[tex]3 \frac{5}{24} \times 1 \frac{43}{77} = \frac{77}{24} \times \frac{120}{77} = 5[/tex]
[tex] \frac{3}{5} \div \frac{12}{10} = \frac{3}{5} \times \frac{10}{12} = \frac{2}{4} = \frac{1}{2} [/tex]
[tex]1 \frac{4}{9} \div \frac{2}{9} = \frac{13}{9} \times \frac{9}{2} = 6 \frac{1}{2} [/tex]
[tex]14 \div 3 \frac{1}{2} = 14 \times \frac{2}{7} = 4[/tex]
[tex]2 \frac{7}{9} \div 25 = \frac{25}{9} \times \frac{1}{25} = \frac{1}{9} [/tex]
