To proof

As given

uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs.

As given in the question

Convert the answer to larger units .

As between yard is the largest unit between yard, feet and inches.

$1 inches = \frac{1}{36} yard$

and

$1 feet = \frac{1}{3} yard$

Convert 2 feet into yard

$=\frac{2}{3}$

Convert 4 inches into yard

$= \frac{4}{36}$

twine to wrap each carton packs

$= 1 + \frac{2}{3} + \frac{4}{36}$

L.C.M of (3 , 36) = 36

than the equation becomes

$=\frac{36 +2\times 12 + 4}{36}$

$= \frac{64}{36}$

=1.77777778 yard

Now twine to wrap pack 29 cartons = 29× 1.77777778
