To find the ratio of the number of full tables to the total number of tables, we first need to determine the total number of tables at Trisha's Italian Restaurant.
The total number of tables is the sum of the full tables and the empty tables:
\[ \text{Total Tables} = \text{Full Tables} + \text{Empty Tables} = 32 + 27 = 59 \]
Now, the ratio of the number of full tables (32) to the total number of tables (59) can be expressed as:
\[ \text{Ratio} = \frac{\text{Number of Full Tables}}{\text{Total Number of Tables}} = \frac{32}{59} \]
Thus, the ratio of the number of full tables to the total number of tables is:
\[ 32:59 \]
