Penyelesaian:
1.
[tex] \frac{5}{7} - \frac{4}{5} = \frac{25}{35} - \frac{28}{35} = - \frac{3}{35} [/tex]
2.
[tex] \frac{6}{3} - \frac{5}{2} = 2 - \frac{5}{2} = - \frac{1}{4} [/tex]
3.
[tex] \frac{12}{4} - \frac{4}{7} = 3 - \frac{4}{7} = \frac{17}{7} [/tex]
4.
[tex] \frac{7}{5} \times \frac{7}{5} = \frac{49}{25} [/tex]
5.
[tex] \frac{8}{4} \times \frac{5}{3} = \frac{40}{12} = \frac{10}{3} [/tex]
6.
[tex] \frac{7}{4} \div \frac{5}{6} = \frac{7}{4} \times \frac{6}{5} = \frac{42}{20} = \frac{21}{10} [/tex]
7.
[tex] \frac{15}{2} \div \frac{4}{3} = \frac{15}{2} \times \frac{3}{4} = \frac{45}{8} [/tex]
8.
[tex] \frac{4}{7} \div \frac{5}{4} = \frac{4}{7} \times \frac{4}{5} = \frac{16}{35} [/tex]
9.
[tex] \frac{11}{3} \div \frac{5}{3} = \frac{11}{3} \times \frac{3}{5} = \frac{11}{5} [/tex]
10.
[tex] \frac{4}{3} \times \frac{5}{7} = \frac{20}{21} [/tex]
