Reduce the Tens Digit: Converting 545 to a New Number

We will solve this problem step-by-step:

• Step 1: Identify the tens digit of 545.
  The number 545 can be broken down into: 500 (hundreds), 40 (tens), and 5 (units). The tens digit is 4.

• Step 2: Reduce the tens digit by 2.
  The tens digit is 4. When reduced by 2, we calculate: $4 - 2 = 2$.

• Step 3: Reconstruct the number.
  Replacing the original tens digit of 4 with 2 results in the number $500 + 20 + 5 = 525$.

Thus, the number after reducing the tens digit by 2 is $525$.

Therefore, the solution to the problem is $525$.
