Questions & Step-by-Step Solutions

What is 1.2 - 0.4?
  • Step 1: Write down the numbers you want to subtract: 1.2 and 0.4.
  • Step 2: Align the numbers by their decimal points: 1.2 and 0.4.
  • Step 3: Subtract the numbers starting from the right: 2 (from 1.2) minus 4 (from 0.4) cannot be done, so we need to borrow 1 from the 1 in 1.2.
  • Step 4: After borrowing, the 1 in 1.2 becomes 0, and the 2 becomes 12. Now, subtract: 12 minus 4 equals 8.
  • Step 5: Now, move to the left side: 0 (after borrowing) minus 0 equals 0.
  • Step 6: Combine the results: The answer is 0.8.
