Answer:
80% of the painters at the construction job are painting the interior of the gallery.
Explanation:
To find the percent of painters who are painting the interior of the gallery, you can divide the number of painters painting the interior by the total number of painters, and then multiply the result by 100%.
In this case, you would do the following calculation:
28 painters / 35 painters * 100% = 80%
thus, 80% of the painters at the construction job are painting the interior of the gallery.
