p/5 = 8/12.5
p = 4
Manuel can paint 5 pictures in 12.5 hours. At this rate, which proportion can be used to
find p, the number of pictures Manuel can paint in 8 hours?

We can use a proportion to solve this problem.
First, we can start with the given information that Manuel can paint 5 pictures in 12.5 hours. We can set up a proportion with the number of pictures he can paint and the time it takes:
5 pictures / 12.5 hours = p pictures / 8 hours
To solve for p, we can cross-multiply:
5 pictures * 8 hours = 12.5 hours * p pictures
40 pictures = 12.5 hours * p pictures
Finally, we can divide both sides by 12.5 to solve for p:
p pictures = 40 pictures / 12.5
p pictures = 3.2
Therefore, Manuel can paint 3.2 pictures in 8 hours at this rate. Since he cannot paint a fraction of a picture, the actual number of pictures he can paint in 8 hours would be either 3 or 4, depending on how close he is to finishing the fourth picture when the 8 hours are up.
