Answer: Option 'D' is correct.
Explanation:
Since we have given that
Number of points they score from normal shots = 32
Number of points they score from three point shots = 18
Number of points they score from free throws = 16
Total points is given by
![32+16+18=66](https://img.qammunity.org/2019/formulas/mathematics/middle-school/1me9c1vnzojbi83pgd8x4cuze1ew0hfucu.png)
so, Ratio of points earned from normal shots to the total points is given by
![32:66\\\\=16:33\\\\or\\\\(16)/(33)\\\\or\\\\16\ to\ 33](https://img.qammunity.org/2019/formulas/mathematics/middle-school/i26sce98slhbhc0x309e81uy25bafpncgi.png)
Hence, option 'D' is correct.
