Answers
3. Given: Total no. of marbles = 642
No. of marbles that can be put in 1 packet = 22
To Find: The no. of packets required and no. of marbles
left.
Solution : 22 marbles -------- 1 packet
642 marbles ------- ? packets
Therefore, No. of packets= 642/22 = 29.1818
Since no. of packets cannot be a decimal, thus the no. of packets is 29.
As all the marbles are not accommodated in 29 packets, the no. of marbles left will be :
= total no. of marbles - (no. of marbles in 1 packet × 29)
= 642 - ( 22×29 )
= 642 - 638
= 4
Answer: The no. of packets required = 29
The no. of marbles left = 4
4. Given: Total no. of stamps = 526
No. of stamps that 1 page of the album hold= 25
To Find: The no. of pages used and no. of stamps left
Solution: 25 stamps -------- 1 page
526 stamps ------- ? pages
Therefore, No. of pages = 526/25 = 21.04
Since no. of pages cannot be a decimal, thus the no. of pages used is 21.
As all the stamps are not accommodated in 21 pages, the no. of stamps left will be :
= total no. of stamps - (no. of stamps on 1 page × 21)
= 526 - ( 25×21 )
= 526 - 525
= 1
Answer: The no. of pages used = 21
The no. of stamps left = 1
