Question

The section of the boardwalk shown is made using boards that are each 9 1/4 inches wide. The spacing between each board is equal. What is the width of the spacing between each board?

Answer 1

.375 or 3/8

Explanation:

Make 9 1/4 into an improper fraction that is 37/4

37/4 × 15 = 555/4

554/4= 138.5

144-138.5= 5.5

5.50/14 = .375
