What three numbers have an average of 300?

Part 1: Understanding the Problem

We're looking for three numbers whose average is 300. This means if we add these three numbers together and divide by 3, we should get 300.

Step-by-step Solution:

  1. Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
  2. In this case: 300 = (x + y + z) / 3
  3. To find the sum, multiply both sides by 3: 300 * 3 = x + y + z
  4. So, the sum of our three numbers should be: 900

Part 2: Finding Solutions

Now, let's find multiple sets of three numbers that add up to 900.

Solution 1:

300, 300, 300

Verification:

(300 + 300 + 300) / 3 = 900 / 3 ≈ 300

This solution is correct!

Solution 2:

300, 300, 300

Verification:

(300 + 300 + 300) / 3 = 900 / 3 ≈ 300

This solution is correct!

Solution 3:

471, 42, 387

Verification:

(471 + 42 + 387) / 3 = 900 / 3 ≈ 300

This solution is correct!

Solution 4:

440, 46, 414

Verification:

(440 + 46 + 414) / 3 = 900 / 3 ≈ 300

This solution is correct!

Solution 5:

60, 90, 750

Verification:

(60 + 90 + 750) / 3 = 900 / 3 ≈ 300

This solution is correct!
