Final answer:
To find the percent of paintings displayed on the first floor, divide the number of paintings displayed by the total number of paintings and then multiply by 100.
Step-by-step explanation:
To find the percent of paintings displayed on the first floor, you can use the formula:
Percent = (Number of paintings displayed / Total number of paintings) x 100
Plug in the given values:
Number of paintings displayed = 40
Total number of paintings = 92
So, the percent of paintings displayed on the first floor is:
Percent = (40 / 92) x 100 = 43.48%
