Answer:
Shelf can hold 20 books.
Step-by-step explanation:
Consider the provided information.
You have a shelf that holds 25 1/2 pounds
This can be written as:
[tex]25\frac{1}{2}=\frac{51}{2}=25.5[/tex]
We need to find how many 1 1/4 pound books can the shelf hold.
[tex]1\frac{1}{4}=\frac{5}{4}=1.25[/tex]
Thus the shelf can hold:
[tex]\frac{25.5}{1.25}=20.4\approx 20[/tex]
That means Shelf can hold 20 such books.
