Using proportions, it is found that both spaces have the same brightness, as both have 3 candles per m².
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For Nayeli and Citlali, the rate of candles per m² is given by:
- N = 12/4 = 3 candles per m².
- C = 30/10 = 3 candles per m².
Hence both spaces have the same brightness, as both have 3 candles per m².
