To find the ratio of balls hit to left field to balls hit to right field, we first identify the numbers:
- Balls hit to right field: 15
- Balls hit to left field: 7
The ratio of balls hit to left field to balls hit to right field is:
\[ \text{Ratio} = \frac{\text{Balls hit to left field}}{\text{Balls hit to right field}} = \frac{7}{15} \]
Now, we convert this fraction to a decimal by dividing 7 by 15:
\[ \frac{7}{15} \approx 0.4667 \]
Rounding this to the nearest hundredth, we find:
\[ 0.47 \]
Thus, the ratio of balls hit to left field to balls hit to right field, represented as a decimal and rounded to the nearest hundredth, is 0.47.
