Step-by-Step Solution
Solution:

  1. Step 1: Understand division with integers in PowerShell

    PowerShell automatically converts to floating-point when dividing integers if result is not whole.

  2. Step 2: Calculate 7 divided by 2

    7 / 2 = 3.5, a floating-point number.

  3. Final Answer:

    3.5 -> Option B

  4. Quick Check:

    Integer division returns float if needed = 3.5 [OK]
Quick Trick: Division returns float if not exact integer [OK]
Common Mistakes:
  • Expecting integer truncation
  • Thinking division causes error
  • Confusing 3.0 with 3.5
