Answer: D.45 inches, 75 inchesStep-by-step explanation:Hi, to answer this question, first, we have to divide the board’s length by the number of parts that conforms the 2 sections.

Since the ratio is 3/5, one section is made of 3 parts and the other section is made of 5 parts. 3+5 = 8 parts

120 / 8 = 15 inches

Each part measures 15 inches.

Now, we have to multiply each part’s length by the number of parts that each section has. (3 and 5)

15x 3 = 45 inches

15 x 5 = 75 inches
