Subtract 0.9289 and 0.7493. The difference is
A. 0.2216
B. 0.1796
C. 1.6782
D. 0.0796
The correct answer and explanation is:
The correct answer is B. 0.1796.
To solve this, you need to subtract 0.7493 from 0.9289.
- Start with the subtraction: 0.9289−0.74930.9289 – 0.7493
- Align the decimal points to keep the numbers in the correct place value order: 0.9289−0.74930.9289 – 0.7493
- Subtract each column, starting from the rightmost digit:
- In the thousandths place: 9 – 3 = 6
- In the hundredths place: 8 – 9. Since 8 is less than 9, borrow 1 from the tenths place (making the 2 become 1). Now, 18 – 9 = 9.
- In the tenths place: After borrowing, 1 – 4 is not possible, so you need to borrow 1 from the ones place (making the 9 become 8). Now, 11 – 4 = 7.
- In the ones place: 8 – 7 = 1.
Thus, the difference between 0.9289 and 0.7493 is 0.1796.
In subtraction, it’s crucial to align the decimal points and handle borrowing correctly, especially when subtracting digits where the top number is smaller than the bottom one.
