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:
\(25\frac{1}{2}=\frac{51}{2}=25.5\)
We need to find how many 1 1/4 pound books can the shelf hold.
\(1\frac{1}{4}=\frac{5}{4}=1.25\)
Thus the shelf can hold:
\(\frac{25.5}{1.25}=20.4\approx 20\)
That means Shelf can hold 20 such books.
