A section of a boardwalk is made using 15 boards. Each board is 9 1/4 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.
I just did this
well, you fixed that 914
I used 9.14
but you can use my solution with 9.25
here it is using 9.14

To find the width of the spacing between each board, we need to subtract the total width of the boards from the total width of the section.
The total width of the boards can be calculated by multiplying the number of boards (15) by the width of each board (9 1/4 inches).
15 boards × 9 1/4 inches/board = (15 × 9) inches + (15 × 1/4) inches = 135 inches + 3.75 inches = 138.75 inches
Now, to find the width of the spacing between each board, we need to subtract the width of the boards from the total width of the section.
144 inches - 138.75 inches = 5.25 inches
Therefore, the width of the spacing between each board is 5 1/4 inches.
