Reduce these ratios to lowest terms.

1) 60:15 = [tex]\color{lime}{{\tt{4 : 1}}}[/tex]
2) 75:25 = [tex]\color{lime}{{\tt{3 : 1}}}[/tex]
3) 45:15 = [tex]\color{lime}{{\tt{3 : 1}}}[/tex]
4) 25:5 = [tex]\color{lime}{{\tt{5 : 1}}}[/tex]

3. There 100 teachers were there.
- 5 : n = 125 : 2,500
- (5 × 2,500) ÷ (125 × n)
- 12,500 ÷ 125n = 100

4. There are 24 male teachers.
- 2 : 9 = n : 108
- (2 × 108) ÷ (9 × n)
- 216 ÷ 9n = 24
