1 ft = 12 in
3 and a half feet = 3.5 ft
3.5 feet = 3.5 ∙ 12 in = 42 in
3 and a half feet = 3.5 ft
3.5 feet = 3.5 ∙ 12 in = 42 in

Not quite.
3 * 12 = 36
1/2 * 12 = 12/2 = 6
36 + 6 = 42
3 1/2 inches * 12 = 42 inches
3 * 12 = 36
1/2 * 12 = 12/2 = 6
36 + 6 = 42
3 1/2 inches * 12 = 42 inches

12 * 3 = 36
12 * 1/2 = 6
and
36 + 6 = 42
note that is halfway between 3 feet (36") and 4 feet (48")
12 * 1/2 = 6
and
36 + 6 = 42
note that is halfway between 3 feet (36") and 4 feet (48")

nope
3 feet times 12 is 36 inches , the other half a foot is 6 inches
you can cancel units just like numbers
... 12 inches per foot ... 12 in/ft
multiply by 3.5 feet (changed to decimal)
(12 in/ft) * (3.5 ft) ... the ft cancel (top and bottom of fraction)
... 12 in * 3.5 = ?
