5 3/8; 5 1/4; 7 1/2 How to find the average?

add them up, then divide by 3

6 1/24

To find the average of a set of numbers, you need to add up all the numbers and then divide the sum by the total number of values in the set.

Let's find the average of the given numbers: 5 3/8, 5 1/4, and 7 1/2.

Step 1: Convert the mixed numbers to improper fractions.

5 3/8 as an improper fraction is (5 * 8 + 3) / 8 = 43/8.

5 1/4 as an improper fraction is (5 * 4 + 1) / 4 = 21/4.

7 1/2 as an improper fraction is (7 * 2 + 1) / 2 = 15/2.

Step 2: Add up all the fractions.

43/8 + 21/4 + 15/2 = (43/8) + (42/8) + (60/8) = 145/8.

Step 3: Simplify the fraction, if necessary.

The fraction 145/8 cannot be simplified any further.

Step 4: Divide the sum by the number of values.

Since we have three numbers in the set, divide 145/8 by 3:

(145/8) ÷ 3 = 145/8 * 1/3 = 145/24 ≈ 6.042.

So, the average of the given numbers is approximately 6.042.
