Baris 83:
# <math>a \times \frac{b}{c} = \frac{a \times b}{c}</math>
# <math>\frac{a}{b} = \frac{c}{d} \Leftrightarrow \frac{b \times c}{a \times d}</math>
Contoh penerapannya, yaitu :
# <math>\frac{2}{3} \times \frac{5}{7} = \frac{2 \times 5}{3 \times 7} = \frac{10}{21}</math>
# <math>2 \times \frac{3}{5} = \frac{2 \times 3}{5} = \frac{6}{5} = 1 \frac{1}{5}</math>
# <math>\frac{2}{3} = \frac{5}{6} \Leftrightarrow \frac{3 \times 5}{2 \times 6} = \frac{15}{12} =1 \frac{3}{12}</math>

Baris 92 ⟶ 97:
<math>\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} \times \frac{d}{c}</math>
Contoh penerapan, yaitu
<math>\frac{2}{3} \div \frac{5}{7} = \frac{2}{3} \times \frac{7}{5} = \frac{14}{15}</math> atau
<math>\frac{\frac{2}{3}}{\frac{5}{7}} = \frac{2}{3} \times \frac{7}{5} = \frac{14}{15}</math>
