What three numbers have an average of 471?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 471. This means if we add these three numbers together and divide by 3, we should get 471.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 471 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 471 * 3 = x + y + z
- So, the sum of our three numbers should be: 1413
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1413.
Solution 1:
471, 471, 471
Verification:
(471 + 471 + 471) / 3 = 1413 / 3 ≈ 471
This solution is correct!
Solution 2:
471, 471, 471
Verification:
(471 + 471 + 471) / 3 = 1413 / 3 ≈ 471
This solution is correct!
Solution 3:
1141, 57, 215
Verification:
(1141 + 57 + 215) / 3 = 1413 / 3 ≈ 471
This solution is correct!
Solution 4:
811, 588, 14
Verification:
(811 + 588 + 14) / 3 = 1413 / 3 ≈ 471
This solution is correct!
Solution 5:
1318, 6, 89
Verification:
(1318 + 6 + 89) / 3 = 1413 / 3 ≈ 471
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 1413 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.
