In Mr. Sneed's classroom, there are 108 tiles and 9 lights. What is the ratio of lights to tiles in Mr. Sneed's classroom?

Answer 1

To find the ratio of lights to tiles in Mr. Sneed's classroom, we need to compare the number of lights to the number of tiles.

There are 9 lights and 108 tiles.

The ratio of lights to tiles can be expressed as:

\[ \text{Ratio} = \frac{\text{Number of lights}}{\text{Number of tiles}} = \frac{9}{108} \]

Next, we simplify the fraction. Both 9 and 108 can be divided by 9:

\[ \frac{9 \div 9}{108 \div 9} = \frac{1}{12} \]

Thus, the ratio of lights to tiles in Mr. Sneed's classroom is:

\[ \boxed{1:12} \]
