Question
3 children ages 2, 4, and 6. what was their average age?
Hello,
The average is obtained in two steps:
1. Add up all the numbers
i.e., 2+4+6=12
2. Divide this by the number of terms you have added
i.e., 12/3=4 is the average age.
You can combine these two steps into (2+4+6)/3 = 4
Example: If the age of four people are 4 8 10 14, what would the average be?
Answer: We add up the four numbers and divide it by four.
(4+8+10+14)/4 = 36/4 = 9. So, the average age is 9.
