What three numbers have an average of 526?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 526. This means if we add these three numbers together and divide by 3, we should get 526.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 526 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 526 * 3 = x + y + z
- So, the sum of our three numbers should be: 1578
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1578.
Solution 1:
526, 526, 526
Verification:
(526 + 526 + 526) / 3 = 1578 / 3 ≈ 526
This solution is correct!
Solution 2:
526, 526, 526
Verification:
(526 + 526 + 526) / 3 = 1578 / 3 ≈ 526
This solution is correct!
Solution 3:
78, 789, 711
Verification:
(78 + 789 + 711) / 3 = 1578 / 3 ≈ 526
This solution is correct!
Solution 4:
744, 442, 392
Verification:
(744 + 442 + 392) / 3 = 1578 / 3 ≈ 526
This solution is correct!
Solution 5:
753, 722, 103
Verification:
(753 + 722 + 103) / 3 = 1578 / 3 ≈ 526
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 1578 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.
