**DAV Class 5 Maths Chapter 10 Worksheet 1 Notes**

Division: It is the operation that carries out the distribution of things with each person or in 1 litre/1 kilogram.

The idea of average is not new to us. We all are familiar with the following types of statements:

- The average number of runs scored by Sachin Tendulkar in the series is 68.
- The average mark secured by Raghav is 83%. If we have a group of 4 students we have to divide 24 toffees to them equally. We count the toffees and divide the sum by the number of students then distribute it equally to them, e.g. 24 ÷ 4 = 6. Each child gets 6 toffees.

To find the average of a group of numbers, divide the sum of numbers by the total number of addends.

Example:

Shyam is a vegetable seller. His daily earnings for seven days are ₹ 20, ₹ 26, ₹ 32, ₹ 25, ₹ 27, ₹ 24, ₹ 28. What must be his average daily earnings?

Solution:

Total earning of Shyam for seven days = ₹ 20 + ₹ 26 + ₹ 32 + ₹ 25 + ₹ 27 + ₹ 24 + ₹ 28 = ₹ 182

Number of days = 7

Average daily earning = ₹ 182 ÷ 7 = ₹ 26

Shyam’s average daily earning is ₹ 26.
