Question

Calculate the average of $20$ and $10$ .

00:00 Calculate the average

00:03 To calculate the average, we need to divide the sum by the number of occurrences

00:08 Let's sum up the numbers

00:15 And divide by the number of occurrences (2)

00:20 And this is the solution to the question

To calculate the average of the numbers 20 and 10, we will follow these steps:

Step 1: Add the two numbers together. We have $20 + 10 = 30$ .
Step 2: Divide the sum by the number of values, which is 2. So, we have $\frac{30}{2} = 15$ .

Therefore, the average of 20 and 10 is $15$ .
