To find the ratio of the number of empty parking spots to the total number of parking spots, you can use the following steps:
-
Identify the number of empty parking spots.
In this case, there are 15 empty spots. -
Identify the total number of parking spots.
There are 50 parking spots in total. -
Set up the ratio.
The ratio can be represented as:\[ \text{Ratio} = \frac{\text{Number of empty spots}}{\text{Total number of spots}} = \frac{15}{50} \]
-
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.
