Answer 1

Question:

In a library, 126 copies of a certain book require a shelf length of 3.78 m. How many copies of the same book would occupy shelf length of 4.8 m?

Given :

• In a library 126 books require a shelf length of 3.78m.

To Find:

• How many books would occupy s shelf length of 4.8 m.

Solution:

No. of books required for a shelf length of $3.78 m = 126$

No. of books required for a shelf length $1 m = \frac{126}{3.78}$

No. of books required for a shelf length of $4.8 m = \frac{126}{3.78} \times 4.8 = 160$

So,

No. of books required for a shelf length of $4.8 m = 160$

Hence,

$160$ books would occupy shelf length of $4.8 m.$

Answer 2

Answer:

$126 \div 3.78$
