Answer 1

Explanation:

To find out how much shorter the pencil was after the student completed the project, we need to subtract the final length from the initial length:

7 1/2 - 5 7/8

To subtract these two mixed numbers, we need to convert them to a common denominator. The smallest common multiple of 2 and 8 (the denominators of the fractions) is 8, so we can rewrite the numbers as:

15/2 - 47/8

Now we can find a common denominator of 8:

(15/2) * (4/4) - (47/8) = 30/8 - 47/8

Subtracting the numerators, we get:

-17/8

Therefore, the pencil was 17/8 inches shorter after the student completed the project than when the student started the project. We can simplify this fraction to a mixed number:

-2 1/8

So the answer is C) 2 3/8 inches.
