What three numbers have an average of 674?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 674. This means if we add these three numbers together and divide by 3, we should get 674.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 674 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 674 * 3 = x + y + z
- So, the sum of our three numbers should be: 2022
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2022.
Solution 1:
674, 674, 674
Verification:
(674 + 674 + 674) / 3 = 2022 / 3 ≈ 674
This solution is correct!
Solution 2:
674, 674, 674
Verification:
(674 + 674 + 674) / 3 = 2022 / 3 ≈ 674
This solution is correct!
Solution 3:
1590, 311, 121
Verification:
(1590 + 311 + 121) / 3 = 2022 / 3 ≈ 674
This solution is correct!
Solution 4:
168, 1675, 179
Verification:
(168 + 1675 + 179) / 3 = 2022 / 3 ≈ 674
This solution is correct!
Solution 5:
467, 969, 586
Verification:
(467 + 969 + 586) / 3 = 2022 / 3 ≈ 674
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 2022 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.
