Solve: 17.4-9.8=
The correct answer and explanation is:
The correct answer is:
17.4 – 9.8 = 7.6
Explanation:
This is a simple subtraction problem where you are subtracting 9.8 from 17.4.
Start by lining up the decimal points for clarity:
17.4
- 9.8
-------
Now subtract from right to left, starting with the tenths place.
- Tenths place: Subtract 8 from 4. Since 4 is smaller than 8, you need to borrow 1 from the units place. This makes the 4 in the tenths place become 14. Now, subtract 8 from 14, which gives you 6.
- Units place: After borrowing, the 7 becomes 6. Now subtract 9 from 6. Again, since 6 is smaller than 9, you need to borrow 1 from the tens place. This makes the 17 become 16. Subtract 9 from 16, which gives you 7.
Now you can write the result:
17.4
- 9.8
-------
7.6
Thus, the answer is 7.6. This method of borrowing ensures that you can properly subtract even when the digits in each place value are smaller than the number you are subtracting from them. Subtraction with decimals follows the same principles as whole number subtraction, just with careful attention to decimal points.
