[tex] \frac{12}{8} = \frac{m}{20} \\ 8m = 12 \times 20 \\ m = \frac{240}{8} = 30[/tex]
[tex] \frac{8}{12} = \frac{n}{18} \\ 12n = 8 \times 18 \\ n = \frac{144}{12} = 12[/tex]
b.
[tex] \frac{15}{12} = \frac{p}{16} \\ 12p = 15 \times 16 \\ p = \frac{240}{12} = 20[/tex]
[tex] \frac{12}{15} = \frac{q}{20} \\ 15q = 12 \times 20 \\ q = \frac{240}{15} = 16[/tex]
