To find the answer to the subtraction problem 3.4 - 0.972, you simply subtract the second number from the first number. Here are the steps to calculate it:
Step 1: Write down the subtraction problem: 3.4 - 0.972.
Step 2: Align the numbers vertically, with the decimal points lined up.
3.4
- 0.972
Step 3: Subtract the numbers in the same column from right to left. Start with the ones place (rightmost column) and move towards the left.
- Subtract 2 from 4 (ones place): 4 - 2 = 2.
- Subtract 7 from 3 (tenths place): Since 7 is greater than 3, borrow 1 from the digit on the left (which is 4).
So, the 3 becomes 2 (3 - 1 = 2), and we add a decimal point after it.
Then subtract 7 from 12: 12 - 7 = 5.
- Subtract 9 from 2 (hundredths place): Since 9 is greater than 2, borrow 1 from the digit on the left (which is 2).
So, the 2 becomes 1 (2 - 1 = 1), and we continue with the subtraction.
Then subtract 9 from 12: 12 - 9 = 3.
Step 4: Write down the answers below each column.
3.4
- 0.972
--------
2.428
Therefore, the answer to the subtraction problem 3.4 - 0.972 is 2.428.
