IV. Solve each proportion.
16. [tex]\frac{5}{12}[/tex] = [tex]\frac{35}{n}[/tex]
5 × n = 5n
12 × 35 = 420
420 ÷ 5n = 84
[tex]\boxed{n = 84}{}[/tex]
17. [tex]\frac{n}{4}[/tex] = [tex]\frac{24}{6}[/tex]
n × 6 = 6n
4 × 24 = 96
96 ÷ 6n = 16
[tex]\boxed{n = 16}{}[/tex]
18. [tex]\frac{n}{52}[/tex] = [tex]\frac{180}{120}[/tex]
n × 120 = 120n
52 × 150 = 9 360
9 360 ÷ 120n = 78
[tex]\boxed{n = 78}{}[/tex]
19. [tex]\frac{10}{16}[/tex] = [tex]\frac{n}{56}[/tex]
10 × 56 = 560
16 × n = 16n
560 ÷ 16n = 35
[tex]\boxed{n = 35}{}[/tex]
20. [tex]\frac{18}{n}[/tex] = [tex]\frac{21}{28}[/tex]
18 × 28 = 504
n × 21 = 21n
504 ÷ 21n = 24
[tex]\boxed{n = 24}{}[/tex]
