Video Solution

Solution Steps

00:00 Calculate the average
00:03 To calculate the average, we need to divide the sum by the number of occurrences
00:07 Let's sum up the numbers
00:12 And divide by the number of occurrences (4)
00:32 Let's break down 24 into 20 plus 3
00:41 Let's break it down into whole number and remainder
00:48 Convert from whole fraction to whole number
00:52 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the sum of the numbers.
  • Step 2: Determine the count of the numbers.
  • Step 3: Use the formula for the average.

Now, let's work through each step:
Step 1: Sum of the numbers = 7+6+5+5=23 7 + 6 + 5 + 5 = 23 .
Step 2: Count of the numbers = 4.
Step 3: Apply the average formula:
Average=234=5.75 \text{Average} = \frac{23}{4} = 5.75 This can be expressed as a mixed number, 534 5\frac{3}{4} .

Therefore, the average of 7, 6, 5, and 5 is 534 5\frac{3}{4} .

Answer

534 5\frac{3}{4}
