Answer 1

To determine how many 3/4 ft long pieces can be cut from a 12 ft long pipe, you can divide the total length of the pipe by the length of each piece:

\[
\text{Number of pieces} = \frac{\text{Total length}}{\text{Length of each piece}} = \frac{12 \text{ ft}}{\frac{3}{4} \text{ ft}}
\]

To divide by a fraction, you multiply by its reciprocal:

\[
\frac{12}{\frac{3}{4}} = 12 \times \frac{4}{3} = \frac{12 \times 4}{3} = \frac{48}{3} = 16
\]

Thus, you can cut **16 pieces** of 3/4 ft long pipe from a 12 ft long pipe.

The answer is **16**.
