What three numbers have an average of 369?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 369. This means if we add these three numbers together and divide by 3, we should get 369.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 369 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 369 * 3 = x + y + z
- So, the sum of our three numbers should be: 1107
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1107.
Solution 1:
369, 369, 369
Verification:
(369 + 369 + 369) / 3 = 1107 / 3 ≈ 369
This solution is correct!
Solution 2:
369, 369, 369
Verification:
(369 + 369 + 369) / 3 = 1107 / 3 ≈ 369
This solution is correct!
Solution 3:
578, 80, 449
Verification:
(578 + 80 + 449) / 3 = 1107 / 3 ≈ 369
This solution is correct!
Solution 4:
764, 176, 167
Verification:
(764 + 176 + 167) / 3 = 1107 / 3 ≈ 369
This solution is correct!
Solution 5:
646, 70, 391
Verification:
(646 + 70 + 391) / 3 = 1107 / 3 ≈ 369
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 1107 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.
