Answer: D. 45 inches, 75 inches
Step-by-step explanation:
To resolve this inquiry, we first need to divide the board's total length by the number of segments forming the two sections.
Given the ratio of 3:5, one section consists of 3 segments and the other of 5, making a total of 8 segments.
120 divided by 8 equals 15 inches for each segment.
Next, we multiply the length of each segment by how many segments each section has (3 and 5).
15 times 3 equals 45 inches.
15 times 5 equals 75 inches.
I believe the answer would be C, based on your previous statements.
