What three numbers have an average of 708?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 708. This means if we add these three numbers together and divide by 3, we should get 708.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 708 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 708 * 3 = x + y + z
- So, the sum of our three numbers should be: 2124
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2124.
Solution 1:
708, 708, 708
Verification:
(708 + 708 + 708) / 3 = 2124 / 3 ≈ 708
This solution is correct!
Solution 2:
708, 708, 708
Verification:
(708 + 708 + 708) / 3 = 2124 / 3 ≈ 708
This solution is correct!
Solution 3:
1368, 664, 92
Verification:
(1368 + 664 + 92) / 3 = 2124 / 3 ≈ 708
This solution is correct!
Solution 4:
556, 1376, 192
Verification:
(556 + 1376 + 192) / 3 = 2124 / 3 ≈ 708
This solution is correct!
Solution 5:
1228, 120, 776
Verification:
(1228 + 120 + 776) / 3 = 2124 / 3 ≈ 708
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 2124 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.
