-inch candle to burn down?
To solve this problem, we can set up a proportion using the given information.
Let "x" be the time it takes for the 15 ¾-inch candle to burn down.
We can set up the following proportion:
8 ¾ : 4 = 15 ¾ : x
To simplify the proportion, convert all the fractions to improper fractions:
35/4 : 4 = 63/4 : x
Now, cross multiply:
(35/4) * x = (4) * (63/4)
Simplify:
35x = 252
x = 252/35
Simplify the fraction:
x = 7.2
Therefore, it would take approximately 7.2 hours for the 15 ¾-inch candle to burn down.
