A blue candle is twice as long as a red candle. The blue candle takes 6 hours to burn out and the red candle takes 15. After 5 hours, what fractional part of each candle is left? The blue candle’s length is what fraction of the red candle’s length? Explain how you got your answer.
The blue candle will be 5/6 of the way burned, the red candle will be 1/3 of the way burned. This is because it has been five hours, and therefore because the total of the red candle is fifteen, and five divided by fifteen is one third
