What is a Dozen?

Dozen is one of the most primitive and easiest customary units of numbers. The number system with the base number 12 is known as duodecimal or dozenal. A dozen is a grouping of exactly twelve numbers, shapes, or objects. It can be written as doz or dz. Hence, 1 dozen equals to 12. The start of the dozen is believed to be started with the counting of the finger bones using the thumb. It is related to nature.

Examples of Dozen

Example 1: Suresh bought 4 dozen bananas. How many bananas did he buy?

Solution: Each dozen bananas has 12 bananas.

So, 4 dozen will have 4 × 12 = 48 bananas.

Example 2: Peter ordered 60 bottles of cold drink for his birthday party. The bottles came in boxes of dozen. How many boxes were there?

Solution: Each box has a dozen bottles, that is, 12 bottles.

In order to calculate how many numbers of dozen are in 60, we will divide 60 by 12.

60 ÷ 12 = 5.

Therefore, there were 5 boxes of bottles.
