Answer:

12 slats can be made from a board i,e 42 feet long

Explanation:

As per the given statement: A fence builder uses boards
3(1)/(2) feet long for the vertical slats on the fence.

We have to calculate how many slats can be made from a board that is 42 feet long.

Builder uses board
3(1)/(2) = (7)/(2) feet long for the vertical slats.

then;

for 42 feet long =
(42)/((7)/(2) ) = 42 * (2)/(7) = 6 * 2 = 12 slats can be made.

Therefore, 12 slats can be made from a board that is 42 feet long.
