If the average of five numbers is 20, what is the total sum of these numbers?

If the average of five numbers is 20, what is the total sum of these numbers?

Step 1: Understand that the average of a set of numbers is calculated by dividing the total sum of those numbers by the number of items.
Step 2: In this case, we know the average is 20 and there are 5 numbers.
Step 3: To find the total sum, we can use the formula: Total sum = Average * Number of items.
Step 4: Substitute the values into the formula: Total sum = 20 * 5.
Step 5: Calculate the result: 20 * 5 = 100.
Step 6: Therefore, the total sum of the five numbers is 100.

Average Calculation – Understanding that the average is the total sum of numbers divided by the count of numbers.
Multiplication for Total Sum – Using multiplication to find the total sum from the average and the number of items.
