21, colon, 1521:15
3, colon, 23:2
19, colon, 1319:13
36, colon, 2436:24
12, colon, 1812:18

Answer 1

First simplify 18:12. GCD(18,12)=6, so 18:12 = 3:2.

Now check each option:
- 21:15 = 7:5 → no
- 3:2 → yes
- 19:13 → no
- 36:24 = (divide by 12) 3:2 → yes
- 12:18 = 2:3 → no

Equivalent ratios: 3:2 and 36:24.
