14. [tex]\boxed{{\tt{\color{lime}{16}}}}[/tex] : 4 = 24 : 6
[tex]n \times 6 = 6n[/tex]
[tex]4 \times 24 = 96[/tex]
[tex]96 \div 6 = 16[/tex]
[tex]\\[/tex]
15. 10 : 6 = [tex]\boxed{{\tt{\color{lime}{93.4}}}}[/tex] : 56
[tex]10 \times 56 = 560[/tex]
[tex]6 \times n = 6n[/tex]
[tex]560 \div 6n = 93.4[/tex]
[tex]\\[/tex]
16. 2/4 = [tex]\boxed{{\tt{\color{lime}{4}}}}[/tex]/8
[tex] \frac{2 \times 8}{4 \times n} = \frac{16}{4n} \div \frac{4}{4} = \frac{4}{n} [/tex]

17. 5/10 = 5/[tex]\boxed{{\tt{\color{lime}{10}}}}[/tex]
[tex] \frac{5 \times n = 5n}{10 \times 5 = 50}[/tex]
[tex]50 \div 5n \: = 10[/tex]
[tex]\\[/tex]
18. [tex]\boxed{{\tt{\color{lime}{9}}}}[/tex]/24 = 3/8
[tex]n \times 8 = 8n \\ 24 \times 3 = 72 \\ 72 \div 8n = 9[/tex]
[tex]\\[/tex]
19. 18/36 = [tex]\boxed{{\tt{\color{lime}{5}}}}[/tex]/10
[tex]18 \times 10 = 180 \\ 36 \times n = 36n \\ 180 \div 36n = 5[/tex]
[tex]\\[/tex]
20. 69/[tex]\boxed{{\tt{\color{lime}{138}}}}[/tex] = 3/6
[tex]69 \times 6 = 414 \\n \times 3 = 3n \\ 414 \div 3n = 138[/tex]
