Answer: 43 1/12 inches

Step-by-step explanation:

Since Amy Ami cut 6 3/4 inches off a long roll of paper and the roll is now 36 1/3, the length of the original roll of paper will be:

= 6 3/4 + 36 1/3

Note that the LCM of 4 and 3 is 12.

= 6 3/4 + 36 1/3

= 6 9/12 + 36 4/12

= 42 13/12

= 43 1/12 inches
