Given the the total number of paintings and prints that an artist has which is 240, and the ratio is 3 of paintings is to 5 prints, here is the answer as to what the ratio is of the remaining paintings to prints. Given that the total number is 240 with the ratio of 3 : 5, this would mean that there are a total of 90 paintings and 150 prints. Since 15 paintings and 100 prints are sold, this would leave us 75 paintings and 50 prints. The new ratio would be 3 : 2. Hope this answer helps.
