What is 3.87 minus 1.95?

• A. 1.90
• B. 1.92
• C. 2.00
• D. 1.88

Answer: (B)

When you subtract decimals, line up the decimal points and work from right to left, borrowing as needed. A clean way is to think in hundredths.

3.87 is 387 hundredths and 1.95 is 195 hundredths. Subtract: 387 − 195 = 192 hundredths, which is 1.92.

If you do it step by step in place value: hundredths 7 − 5 = 2; tenths 8 − 9 can’t be done, so borrow 1 from the units (3 becomes 2, and the tenths become 18). Then 18 − 9 = 9 tenths. Finally, units 2 − 1 = 1. Put together: 1.92.

So the exact difference is 1.92. The other options arise from either not borrowing correctly or misaligning the decimal places.
