What three numbers have an average of 536?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 536. This means if we add these three numbers together and divide by 3, we should get 536.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 536 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 536 * 3 = x + y + z
- So, the sum of our three numbers should be: 1608
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1608.
Solution 1:
536, 536, 536
Verification:
(536 + 536 + 536) / 3 = 1608 / 3 ≈ 536
This solution is correct!
Solution 2:
536, 536, 536
Verification:
(536 + 536 + 536) / 3 = 1608 / 3 ≈ 536
This solution is correct!
Solution 3:
444, 317, 847
Verification:
(444 + 317 + 847) / 3 = 1608 / 3 ≈ 536
This solution is correct!
Solution 4:
357, 555, 696
Verification:
(357 + 555 + 696) / 3 = 1608 / 3 ≈ 536
This solution is correct!
Solution 5:
651, 785, 172
Verification:
(651 + 785 + 172) / 3 = 1608 / 3 ≈ 536
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 1608 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.
