Example : There are 24 folders and each has 56 sheets of paper inside it.
How many sheets of paper are there altogether ?
Solution : Number of folders = 24
Number of sheets in each folder = 56
Total number of sheets = 56 × 24
5 6
× 2 4
2 2 4
+ 1 1 2 0
1 3 4 4
Thus, the total number of sheets is 1344.
Example : A carton holds 24 packets of biscuits. Each packet has 12
biscuits. How many biscuits can be packed in 45 cartons ?
Solution : In one carton we can pack 24 × 12 biscuits. (24 × 12 = 288)
In 45 cartons, we can pack 24 × 12 × 45 biscuits.
= (288 × 45) biscuits.
2 8 8
× 4 5
1 4 4 0
+ 1 1 5 2 0
1 2 9 6 0
Therefore, 12960 biscuits can be packed in 45
cartons.
