What three numbers have an average of 714?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 714. This means if we add these three numbers together and divide by 3, we should get 714.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 714 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 714 * 3 = x + y + z
- So, the sum of our three numbers should be: 2142
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2142.
Solution 1:
714, 714, 714
Verification:
(714 + 714 + 714) / 3 = 2142 / 3 ≈ 714
This solution is correct!
Solution 2:
714, 714, 714
Verification:
(714 + 714 + 714) / 3 = 2142 / 3 ≈ 714
This solution is correct!
Solution 3:
577, 1012, 553
Verification:
(577 + 1012 + 553) / 3 = 2142 / 3 ≈ 714
This solution is correct!
Solution 4:
2124, 17, 1
Verification:
(2124 + 17 + 1) / 3 = 2142 / 3 ≈ 714
This solution is correct!
Solution 5:
99, 1016, 1027
Verification:
(99 + 1016 + 1027) / 3 = 2142 / 3 ≈ 714
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 2142 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.
