Answer:
Check the ratio. 3 parts to 5 parts. The original 24 inch long wood will be cut to two lengths, so there are 3 parts making up a short length and 5 parts making up a long length. That is 3+5 = 8 parts. The two resulting pieces are in the ratio of 3 to 5, or 3:5.
Think carefully --- how many parts is the original 24 inch piece of wood? 8 parts!
How do you cut 24 inches into 8 equal parts? Each part is 3 inches. The original 24 inch wood is composed of 8 parts of 3 inches each.
The longer piece, being 5 parts, is 5 parts! The original 24 inch wood is as we found, 8 parts. Ratio of Long resulting piece to original uncut piece is 5:8.
