Step-by-step explanation:
Note that what you multiply to one side, you multiply to the other (same with dividing) for ratios.
4:5 => 4 * 3: 5 * 3 = 12:15
4:5 => 4 * 4: 5 * 4 = 16:20

Answer:
12:5 and 16:20 are equalevent to 4:5
Step-by-step explanation:
12 divided by 3 = 4 (Because 3 x 4 = 12)
15 ÷ 3 =5 (because 5 x 3 = 15, we basicly raised the ration by a scale factor of 3)
12:15 = 4:5
16 ÷ 4 = 4 (because 4 x 4 = 16)
20 ÷ 4 = 5 (4 x 5 = 20 This ratio was raised by a scale factor of 4)
16 : 20 = 4:5
12:5 and 16:20
