What three numbers have an average of 524?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 524. This means if we add these three numbers together and divide by 3, we should get 524.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 524 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 524 * 3 = x + y + z
- So, the sum of our three numbers should be: 1572
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1572.
Solution 1:
524, 524, 524
Verification:
(524 + 524 + 524) / 3 = 1572 / 3 ≈ 524
This solution is correct!
Solution 2:
524, 524, 524
Verification:
(524 + 524 + 524) / 3 = 1572 / 3 ≈ 524
This solution is correct!
Solution 3:
860, 706, 6
Verification:
(860 + 706 + 6) / 3 = 1572 / 3 ≈ 524
This solution is correct!
Solution 4:
749, 720, 103
Verification:
(749 + 720 + 103) / 3 = 1572 / 3 ≈ 524
This solution is correct!
Solution 5:
25, 1036, 511
Verification:
(25 + 1036 + 511) / 3 = 1572 / 3 ≈ 524
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 1572 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
