What three numbers have an average of 706?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 706. This means if we add these three numbers together and divide by 3, we should get 706.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 706 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 706 * 3 = x + y + z
- So, the sum of our three numbers should be: 2118
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2118.
Solution 1:
706, 706, 706
Verification:
(706 + 706 + 706) / 3 = 2118 / 3 ≈ 706
This solution is correct!
Solution 2:
706, 706, 706
Verification:
(706 + 706 + 706) / 3 = 2118 / 3 ≈ 706
This solution is correct!
Solution 3:
48, 1772, 298
Verification:
(48 + 1772 + 298) / 3 = 2118 / 3 ≈ 706
This solution is correct!
Solution 4:
406, 1062, 650
Verification:
(406 + 1062 + 650) / 3 = 2118 / 3 ≈ 706
This solution is correct!
Solution 5:
222, 757, 1139
Verification:
(222 + 757 + 1139) / 3 = 2118 / 3 ≈ 706
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 2118 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.
