To find the ratio of the number of burgers without onions to the total number of burgers, we need to follow these steps:
-
Calculate the total number of burgers.
- Burgers with onions = 28
- Burgers without onions = 11
- Total burgers = 28 + 11 = 39
-
Determine the number of burgers without onions.
- Burgers without onions = 11
-
Now we can find the ratio of burgers without onions to the total number of burgers: \[ \text{Ratio} = \frac{\text{Burgers without onions}}{\text{Total burgers}} = \frac{11}{39} \]
Therefore, the ratio of the number of burgers without onions to the total number of burgers is \( \frac{11}{39} \).
