Answer:
20 books
Step-by-step explanation:
given that the shelf can hold 25 1/2 lbs (i.e 25.5 lbs), and that each book weighs 1 1/4 ln (i.e 1.25 lbs)
number of books which the shelf can hold
= weight that the shelf can hold ÷ weight of each book
= 25.5 ÷ 1.25
= 20.4 books
because having 0.4 of a book (i.e part of a book) would not be very feasable, we have to round the number of books down to the nearest whole number)
20.4 books rounded down to nearest whole number = 20 books (answer)
