What three numbers have an average of 533?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 533. This means if we add these three numbers together and divide by 3, we should get 533.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 533 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 533 * 3 = x + y + z
- So, the sum of our three numbers should be: 1599
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1599.
Solution 1:
533, 533, 533
Verification:
(533 + 533 + 533) / 3 = 1599 / 3 ≈ 533
This solution is correct!
Solution 2:
533, 533, 533
Verification:
(533 + 533 + 533) / 3 = 1599 / 3 ≈ 533
This solution is correct!
Solution 3:
60, 1299, 240
Verification:
(60 + 1299 + 240) / 3 = 1599 / 3 ≈ 533
This solution is correct!
Solution 4:
272, 327, 1000
Verification:
(272 + 327 + 1000) / 3 = 1599 / 3 ≈ 533
This solution is correct!
Solution 5:
1406, 63, 130
Verification:
(1406 + 63 + 130) / 3 = 1599 / 3 ≈ 533
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 1599 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.
