Only 5% of the junior students got this Australian Mathematics Competition question right (8% of the intermediate students, and 15% of the senior students got it right). There are two candles: a shorter one that burns for 10 hours and a longer one which burns for 7 hours. After 4 hours of burning, the candles are the same height. What is the ratio of the shorter candle's height divided by the longer candles height? To answer the question I'll show you how to write down the information as an algebraic equation. Many people struggle with this (turning a word problem into an equation), so I'll show you how to do a guess and check first and then turn that into an equation.
