Question

A section of a boardwalk is made using 15 boards. Each board is 914914 inches wide. The total width of the section is 144 inches. The spacing between each board is equal. What is the width of the spacing between each board? Write your answer in simplest form.

Answer 1

15 times 9.25 = 138.75 inches.
That leaves

144-138.75 = 5.25 inches for spaces. 
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.

Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches

= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)

Answer 2

Answer

3/8 inch

Step-by-step explanation:

15x9.25 = 138.75

Subtract this number from the total width

144-138.75 = 5.25 inches left for spaces

In an area with 15 boards, there are 14 spaces.

So divide 5.25 by 14 to get

3/8
