To find the ratio of the number of people who like watching basketball to the number of people who do not like watching basketball, we have the following numbers:
- Number of people who like watching basketball: 25
- Number of people who do not like watching basketball: 4
The ratio can be expressed as:
\[ \text{Ratio} = \frac{\text{Number of people who like watching basketball}}{\text{Number of people who do not like watching basketball}} = \frac{25}{4} \]
This ratio can also be simplified or expressed in different ways, but in its simplest form, it is:
\[ \text{Ratio} = 25:4 \]
Thus, the ratio of the number of people who like watching basketball to the number of people who do not like watching basketball is \( 25:4 \).
