# How many 27 in. boards can be cut from 3 boards that are each 7 ft. long?

Nine

#### Explanation:

$\text{1 foot}$$=$$\text{12 inches}$

Determine the number of inches in a $\text{7 ft}$ long board.

$7 \text{ft"xx("12 in")/(1"ft")="84 in}$

Divide the length of each board in inches by $\text{27 in}$.

$\left(84 \text{in")/(27"in}\right) = 3.1$

So three $\text{27-in}$ boards can be cut from $1$ board that is $\text{7 ft}$ long. The $.1$ does not count.

So nine $\text{27-in}$ boards can be cut from $3$ boards that are $\text{7ft}$ in length.
