A rucksack can hold a maximum of 6 kg.

A particular textbook has a mass of 680 g.

What is the maximum number of these textbooks that the rucksack can hold

9 textbooks!

Step-by-step explanation:

Rucksack can hold = 6kg

Mass of textbook = 680g

So, here we need to show the division for finding the number of textbooks it can hold.

680 g in KG's = 0.68

Now, 6/0.68

That is 8.82 (Round off = 9 textbooks)

(convert the 6kg to g first)

1kg = 1000

6kg=6000

6000 : 680 = 8,82

the rucksack can hold between 8 and 9 textbooks
