What three numbers have an average of 500?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 500. This means if we add these three numbers together and divide by 3, we should get 500.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 500 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 500 * 3 = x + y + z
- So, the sum of our three numbers should be: 1500
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1500.
Solution 1:
500, 500, 500
Verification:
(500 + 500 + 500) / 3 = 1500 / 3 ≈ 500
This solution is correct!
Solution 2:
500, 500, 500
Verification:
(500 + 500 + 500) / 3 = 1500 / 3 ≈ 500
This solution is correct!
Solution 3:
713, 207, 580
Verification:
(713 + 207 + 580) / 3 = 1500 / 3 ≈ 500
This solution is correct!
Solution 4:
1171, 27, 302
Verification:
(1171 + 27 + 302) / 3 = 1500 / 3 ≈ 500
This solution is correct!
Solution 5:
1387, 32, 81
Verification:
(1387 + 32 + 81) / 3 = 1500 / 3 ≈ 500
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 1500 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.
