Using quotes around the number makes it a string, not an integer.

Using an integer instead of a floating-point number.

Using 'FullName' which gives the full type name, not just the simple name.

Fill all three blanks to create a hashtable with integer keys and floating-point values (some greater than 2.5).

PowerShell

$data = @{1 = [1]; 2 = [2]; 3 = [3]
$result = @{}
foreach ($key in $data.Keys) {
  if ($data[$key] -gt 2.5) {
    $result[$key] = $data[$key]
  }
}
$result

💡 Hint

Common Mistakes

Using integers instead of floating-point numbers.

Using only values less than or equal to 2.5 which will all be filtered out.

The hashtable has values 1.5, 3.0, and 4.5. The script filters values greater than 2.5, so 3.0 and 4.5 are included.
