Each friend gets 4 pastries.

Number of groups
↓

So, 12 ÷ 3 = 4 → Number to be put in each group
↑

Total number
So, 12 pastries shared equally among 3 friends means dividing 12 by
3 to get 4. Thus, we have found the number to be put in each group.

Example 2: Ashish has 40 stamps. He wants to paste 10 stamps on each page. How
many pages does he require to paste all the stamps?

Solution:

He pastes 10 stamps on the He pastes 10 stamps on the
first page. second page.

He pastes 10 stamps on the He pastes 10 stamps on the
third page. fourth page.

Now he has no more stamps left. So he requires 4 pages to paste 40
stamps.

To paste 40 stamps in groups of 10, we need 4 pages.

Number to be put in each group A Challenge!
↓ A street that is 40 m long
40 ÷ 10 = 4 → Number of groups has a tree every 10 m on
both sides. How many
↑ total trees are there on
Total number the entire street?

Thus, we have found the number of groups.
