Answer:
2
Explanation:
If the doors for the small cabinets are 17.5 in long, and the doors for the large cabinets are 3.5 times longer, find the length of the large cabinet doors by multiplying the length of the small cabinet doors by 3.5:
⇒ Length of large cabinet doors = 17.5 × 3.5 = 61.25 in
1 foot = 12 inches
⇒ 12 foot = 12 × 12 = 144 inches
To find how many large doors can be cut from a board that is 12 feet long, divide 144 inches by the found length of the large door:
⇒ 144 ÷ 61.25 = 2 r 21.5
Therefore, 2 large doors can be cut from a board that is 12 feet long.
(There will be 21.5 inches of board left over).
