What three numbers have an average of 535?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 535. This means if we add these three numbers together and divide by 3, we should get 535.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 535 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 535 * 3 = x + y + z
- So, the sum of our three numbers should be: 1605
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1605.
Solution 1:
535, 535, 535
Verification:
(535 + 535 + 535) / 3 = 1605 / 3 ≈ 535
This solution is correct!
Solution 2:
535, 535, 535
Verification:
(535 + 535 + 535) / 3 = 1605 / 3 ≈ 535
This solution is correct!
Solution 3:
580, 420, 605
Verification:
(580 + 420 + 605) / 3 = 1605 / 3 ≈ 535
This solution is correct!
Solution 4:
503, 663, 439
Verification:
(503 + 663 + 439) / 3 = 1605 / 3 ≈ 535
This solution is correct!
Solution 5:
1576, 22, 7
Verification:
(1576 + 22 + 7) / 3 = 1605 / 3 ≈ 535
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 1605 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.
