To find the ratio of the number of empty parking spots to the total number of parking spots, you can use the following steps:

  1. Identify the number of empty parking spots.
    In this case, there are 15 empty spots.

  2. Identify the total number of parking spots.
    There are 50 parking spots in total.

  3. Set up the ratio.
    The ratio can be represented as:

    \[ \text{Ratio} = \frac{\text{Number of empty spots}}{\text{Total number of spots}} = \frac{15}{50} \]

  4. Simplify the ratio.
    Both the numerator and the denominator can be divided by 5:

    \[ \frac{15 \div 5}{50 \div 5} = \frac{3}{10} \]

Therefore, the ratio of the number of empty parking spots to the total number of parking spots is 3:10.
