Place Value Challenge: Increasing the Hundreds Digit in 189

To solve this problem, we'll follow these steps:

• Step 1: Identify the hundreds digit in the number 189, which is 1.
• Step 2: Increase this hundreds digit by 5, resulting in $1 + 5 = 6$.
• Step 3: Construct the new number using the digits: 6 as the hundreds digit, while the tens and units digits remain 8 and 9, respectively.

Now, let's work through each step:

Step 1: Given number is 189. The hundreds digit is the one in the third column from the right.

Step 2: We increase this digit by 5, so the hundreds digit becomes 6.

Step 3: We reconstruct the number with the updated hundreds digit, maintaining the tens and ones digits as they are: 6 (hundreds) + 8 (tens) + 9 (ones).

Therefore, the new number is $689$.
