Question

1/2 inch= 3 feet what is the length for 7 inches

Answer 1

If $\frac{1}{2}$ inch is equal to 3 feet, then 1 inch = 6 feet because $\frac{1}{2} * 2 = 1$ and 3 * 2 = 6.

Thus 1 x 7 = 7, and 6 x 7 = 42.

42 feet.

Answer 2

If 1/2 inch=3 feet, so, 1 feet=6 feet.
Therefore, 7*6=42 feet
So, your answer should be 42 feet.
