Answer:
7/8
Step-by-step explanation:
First, we need to calculate the percentage of shots that are worth 30 points. This percentage can be calculated as
100% - 25% - 40% = 35%
Because 100% is the total, 25% were worth 50 points and 40% were worth 40 points.
Now, we know that 35% is worth 30 points and 40% is worth 40 points. So, the ratio of 30 points shot to 40 points shot is
35/40 = 7/8
Therefore, the answer is 7/8
