What is division?

Division in mathematics is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. For example, dividing 15 by 3 means splitting 15 into 3 equal groups of 5.

According to the question

Unit price of 8 AA batteries

= 6.24 ÷ 8

= 0.78

Unit price of 20 AA batteries

= 15.8 ÷ 20

= 0.79
