space of 60 books = 1.5m = 150cm
space for one book = 150/60 = 2.5cm
no of books occupy the space of 80cm = 80/2.5 = 32books

Answer:
36
Step-by-step explanation:
no.of book -60|x2
shelf lenght -1.5|80
direct proportion ,
1m=100cm
1.5m=1.5×100=150
60/150=x2/80
2/5×80
2×16=32
×2=32
Therefore, 32 books are needed to fill the shelf
