Wade Kelley · Answer 1

It appears that the ounces tripled equals the hours that the candle can burn. 20 times 3 is 60, 12 times 3 is 36, so multiply 9 by 3 and you will have your answer.

Ahmed Ewing · Answer 2

Because the ratio for both candles is 20/60 or 1/3 then take the number of ounces the candle has and divide by 1/3. In expression: 9 / 1/3 = > 9 * 3 = 18
