Answer:

The 20 books will fit without problems on the shelf.

Explanation:

Given that a maths textbook is 1/2 inches thick and the shelf in the maths classroom is 34 '1/2 inches long, to determine if a set of 20 books will fit on the shelf, the following calculation must be performed:

1/2 = 0.5

34 1/2 = 34.5

34.5 - (20 x 0.5) = X

34.5 - 10 = X

24.5 = X

Thus, it is shown that the 20 books will fit without problems on the shelf.
