    Answer: D.45 inches, 75 inches

    Step-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
