Answer 2

Answer : A

Elio makes candles that are 14, space cm tall. Each candle burns 8 hours before going out.

Let h be the number of hours a 21 cm tall candle burns

14 cm candle burns for 8 hours

21 cm candle burns for h hours

We make a proportion

Ratio of height (cm) = Ratio of hours

So proportion becomes

`(21)/(14) = (h)/(8)`
