A health organization surveyed 600 randomly selected adults about their daily fruit and vegetable intake. The results are summarized in the table below.
| Intake Level | Frequency |
|---|---|
| Meets recommended intake | 210 |
| Close to recommended intake | 180 |
| Below recommended intake | 150 |
| Rarely consumes | 60 |
Based on the survey, what is the best estimate of the ratio of the number of adults who 'meet recommended intake' to the number of adults who 'rarely consume' fruits and vegetables, in the total adult population? (Express your answer as a decimal rounded to the nearest tenth.)
