Answer:
21 pieces
Explanation:
In this question, we need to know the highest number of 4-inch boards Jeremy can cut from a 7-foot board.
Firstly, we need to understand that we have a unit problem here that we need to solve. What I am saying is , we need to make sure we have the two lengths in same unit.
Hence, for the sake of convenience, we covert the length of the board to inches.
It should be recalled that 12 inches = 1 foot. Hence, the number of inches in 7 foot would be 12 * 7 = 84 inches
Back to the question, the number of 4 inches pieces that can be obtained from the board would be 84/4 = 21 pieces that are 4-inch in length
