To find the total length of the boards needed, you can set up the multiplication expression as follows:
7 boards × \( \frac{3}{4} \) feet/board
This can be written as:
\[ 7 \times \frac{3}{4} \]
Now, let's calculate it:
\[ 7 \times \frac{3}{4} = \frac{21}{4} \]
To convert \( \frac{21}{4} \) into a decimal or feet, divide 21 by 4:
\[ \frac{21}{4} = 5.25 \] feet.
So, they will need a total of **5.25 feet** of board for the job.
