Answer:
0.75 is less than 1, so the portrait will be smaller than the actual head.
Explanation:
The art teacher has said that the portrait will be 0.75 times as tall as the actual head.
0.75 is less than 1, so the portrait will be smaller than the actual head.
A ratio of 0.75 means that the portrait will be 3/4 the size of the actual head. So, if the actual head is 8 inches tall, the portrait will be 6 inches tall (8*0.75 = 6). Therefore, the portrait will be smaller than the actual head.
