Answer
27

The correct answer is 27 — Write the tens and units together to get 27.

Step-by-step solution

  1. Look at the units place: 0 is less than 3, so borrow 1 from the tens place. This changes 5 to 4 and gives 10 units.
  2. Subtract the units: 10 – 3 = 7. This is the units digit of the answer.
  3. Subtract the tens: 4 – 2 = 2. This is the tens digit of the answer.
  4. Write the tens and units together to get 27.
Common mistake: Failing to borrow from the tens place

Concept tested: Subtraction with borrowing
