What three numbers have an average of 874?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 874. This means if we add these three numbers together and divide by 3, we should get 874.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 874 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 874 * 3 = x + y + z
- So, the sum of our three numbers should be: 2622
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2622.
Solution 1:
874, 874, 874
Verification:
(874 + 874 + 874) / 3 = 2622 / 3 ≈ 874
This solution is correct!
Solution 2:
874, 874, 874
Verification:
(874 + 874 + 874) / 3 = 2622 / 3 ≈ 874
This solution is correct!
Solution 3:
1278, 160, 1184
Verification:
(1278 + 160 + 1184) / 3 = 2622 / 3 ≈ 874
This solution is correct!
Solution 4:
2483, 39, 100
Verification:
(2483 + 39 + 100) / 3 = 2622 / 3 ≈ 874
This solution is correct!
Solution 5:
2428, 185, 9
Verification:
(2428 + 185 + 9) / 3 = 2622 / 3 ≈ 874
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 2622 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.
