What three numbers have an average of 974?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 974. This means if we add these three numbers together and divide by 3, we should get 974.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 974 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 974 * 3 = x + y + z
- So, the sum of our three numbers should be: 2922
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2922.
Solution 1:
974, 974, 974
Verification:
(974 + 974 + 974) / 3 = 2922 / 3 ≈ 974
This solution is correct!
Solution 2:
974, 974, 974
Verification:
(974 + 974 + 974) / 3 = 2922 / 3 ≈ 974
This solution is correct!
Solution 3:
2406, 238, 278
Verification:
(2406 + 238 + 278) / 3 = 2922 / 3 ≈ 974
This solution is correct!
Solution 4:
395, 120, 2407
Verification:
(395 + 120 + 2407) / 3 = 2922 / 3 ≈ 974
This solution is correct!
Solution 5:
731, 1332, 859
Verification:
(731 + 1332 + 859) / 3 = 2922 / 3 ≈ 974
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 2922 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.
