A blue candle is twice as long as a red one. The blue takes 6 hours to burn out and red takes 15 hours. After 5 hours, what fractional part of each is left?
Thanks for your help!
6/6 - 5/6 = 1/6
15/15 - 5/15 = 10/15 = 2/3
Why does the longer candle take longer to burn??
what is 1-5/6?
what is 1-5/15?
To find the fractional part of each candle that is left after 5 hours, we need to first determine how much of each candle burns in 5 hours.
Let's start with the blue candle. If the blue candle takes 6 hours to burn completely, then in 5 hours, it will burn 5/6 of its length.
Next, let's consider the red candle. If the red candle takes 15 hours to burn completely, then in 5 hours, it will burn 5/15 of its length.
Now that we know how much of each candle burns in 5 hours, we can calculate the fractional part that is left for each candle.
For the blue candle, if it burns 5/6 of its length in 5 hours, then the fractional part that is left is 1 - (5/6) = 1/6.
For the red candle, if it burns 5/15 of its length in 5 hours, then the fractional part that is left is 1 - (5/15) = 2/3.
Therefore, after 5 hours, the blue candle has 1/6 of its length left, while the red candle has 2/3 of its length left.
