Questions & Step-by-Step Solutions
What is 7.2 - 4.5?
- Step 1: Write down the numbers you want to subtract: 7.2 and 4.5.
- Step 2: Align the numbers by their decimal points: 7.2 and 4.5.
- Step 3: Subtract the numbers starting from the right: 2 (from 2) - 5 (from 5) cannot be done, so we need to borrow 1 from the 7.
- Step 4: After borrowing, the 7 becomes 6, and the 2 becomes 12. Now subtract: 12 - 5 = 7.
- Step 5: Now move to the next column: 6 (from 6) - 4 (from 4) = 2.
- Step 6: Combine the results: 2 (from the second column) and 7 (from the first column) gives you 2.7.
- Step 7: Therefore, 7.2 - 4.5 = 2.7.
