There are 93 chairs in the auditorium. 85 of the chairs are red and the rest are blue. What is the ratio of the number of red chairs to the number of blue chairs?

Answer 1

To find the number of blue chairs, we subtract the number of red chairs from the total number of chairs:

\[ \text{Number of blue chairs} = \text{Total chairs} - \text{Red chairs} = 93 - 85 = 8 \]

Now, we find the ratio of the number of red chairs to the number of blue chairs:

\[ \text{Ratio of red to blue chairs} = \frac{\text{Number of red chairs}}{\text{Number of blue chairs}} = \frac{85}{8} \]

Thus, the ratio of the number of red chairs to the number of blue chairs is:

\[ \frac{85}{8} \]

We can also express this ratio in a more readable format:

The ratio of the number of red chairs to blue chairs is \( 85:8 \).
