What three numbers have an average of 692?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 692. This means if we add these three numbers together and divide by 3, we should get 692.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 692 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 692 * 3 = x + y + z
- So, the sum of our three numbers should be: 2076
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2076.
Solution 1:
692, 692, 692
Verification:
(692 + 692 + 692) / 3 = 2076 / 3 ≈ 692
This solution is correct!
Solution 2:
692, 692, 692
Verification:
(692 + 692 + 692) / 3 = 2076 / 3 ≈ 692
This solution is correct!
Solution 3:
861, 969, 246
Verification:
(861 + 969 + 246) / 3 = 2076 / 3 ≈ 692
This solution is correct!
Solution 4:
268, 1362, 446
Verification:
(268 + 1362 + 446) / 3 = 2076 / 3 ≈ 692
This solution is correct!
Solution 5:
1302, 502, 272
Verification:
(1302 + 502 + 272) / 3 = 2076 / 3 ≈ 692
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 2076 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.
