Final answer:
The ratio of lights to tiles in Mr. Sneed's classroom is calculated by dividing 11 lights by 132 tiles, resulting in a ratio of 1:12. Hence, the correct answer is option C (1:12).
Step-by-step explanation:
To find the ratio of lights to tiles, we divide the number of lights by the number of tiles. In Mr. Sneed's classroom, there are 11 lights and 132 tiles. Thus, the ratio of lights to tiles is calculated by dividing 11 (the number of lights) by 132 (the number of tiles).
The calculation will be as follows:
Ratio of lights to tiles = Number of lights ÷ Number of tiles
= 11 ÷ 132
= 1 ÷ 12
So, the simplest form of the ratio is 1:12, which means for every one light there are 12 tiles. Therefore, the correct answer to the question would be option C (1:12).
