What three numbers have an average of 516?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 516. This means if we add these three numbers together and divide by 3, we should get 516.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 516 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 516 * 3 = x + y + z
- So, the sum of our three numbers should be: 1548
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1548.
Solution 1:
516, 516, 516
Verification:
(516 + 516 + 516) / 3 = 1548 / 3 ≈ 516
This solution is correct!
Solution 2:
516, 516, 516
Verification:
(516 + 516 + 516) / 3 = 1548 / 3 ≈ 516
This solution is correct!
Solution 3:
1357, 142, 49
Verification:
(1357 + 142 + 49) / 3 = 1548 / 3 ≈ 516
This solution is correct!
Solution 4:
1488, 48, 12
Verification:
(1488 + 48 + 12) / 3 = 1548 / 3 ≈ 516
This solution is correct!
Solution 5:
1254, 191, 103
Verification:
(1254 + 191 + 103) / 3 = 1548 / 3 ≈ 516
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 1548 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.
