What three numbers have an average of 354?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 354. This means if we add these three numbers together and divide by 3, we should get 354.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 354 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 354 * 3 = x + y + z
- So, the sum of our three numbers should be: 1062
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1062.
Solution 1:
354, 354, 354
Verification:
(354 + 354 + 354) / 3 = 1062 / 3 ≈ 354
This solution is correct!
Solution 2:
354, 354, 354
Verification:
(354 + 354 + 354) / 3 = 1062 / 3 ≈ 354
This solution is correct!
Solution 3:
857, 24, 181
Verification:
(857 + 24 + 181) / 3 = 1062 / 3 ≈ 354
This solution is correct!
Solution 4:
29, 460, 573
Verification:
(29 + 460 + 573) / 3 = 1062 / 3 ≈ 354
This solution is correct!
Solution 5:
562, 273, 227
Verification:
(562 + 273 + 227) / 3 = 1062 / 3 ≈ 354
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 1062 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.
