Final answer:
Joe can saw a wooden plank into m-meter pieces by dividing the total length (n meters) of the plank by the length of each intended piece (m meters). The whole number result is the number of full m-meter pieces possible. Specific values of m and n are required to determine an exact answer.
Step-by-step explanation:
To determine how many m-meter pieces Joe can saw from a wooden plank of n meters, you simply divide the total length of the plank (n) by the length of each piece (m). The result will tell you how many full m-meter pieces can be obtained from the plank. If the division yields a whole number, that is the exact number of pieces Joe can saw.
An easy example to consider would be if Joe has a plank of wood that is 10 meters long (n = 10 m) and he wants to cut it into pieces that are 2 meters long (m = 2 m). He would be able to saw 5 pieces of 2 meters each because 10 divided by 2 equals 5. The answer choices provided (3, 4, 5, 6) cannot be used to accurately answer our question without knowing the specific values of m and n.
