0.2
0.3
0.4
0.5
Subtract tenths by aligning the decimal points: 1.2 ? 0.8 gives 0.4. Watching place values ensures the subtraction is correct. Decimals Subtraction
What is 4.56 + 3.789?
8.345
8.349
8.334
8.435
Align decimals: 4.560 + 3.789. Add thousandths: 0+9=9, hundredths: 6+8=14 (carry 1), tenths: 5+7+1=13 (carry 1), units: 4+3+1=8. Result is 8.349. Decimals Addition
What is 7.05 ? 2.345?
4.650
4.700
4.705
4.750
Convert 7.05 to 7.050 to align three decimal places: 7.050 ? 2.345. Subtract thousandths: 0?5 (borrow) gives 5, then hundredths and tenths accordingly, yielding 4.705. Decimals Subtraction
What is 12.3 + 4.67?
16.79
16.87
16.97
17.00
Align decimals as 12.30 + 4.67. Add hundredths: 0+7=7, tenths: 3+6=9, units: 12+4=16, so 16.97. Proper alignment avoids errors. Decimals Addition
What is 8.2 ? 5.678?
2.502
2.522
2.512
2.520
Convert 8.2 to 8.200, then subtract 5.678. Compute thousandths: 0?8 (borrow) = 2, then hundredths and tenths, resulting in 2.522. Aligning decimals is crucial. Decimals Subtraction
What is 13.456 + 7.89?
21.345
21.346
21.356
21.436
Align as 13.456 + 7.890. Add thousandths: 6+0=6, hundredths: 5+9=14 (carry 1), tenths: 4+8+1=13 (carry 1), units: 13+7+1=21, giving 21.346. Decimals Addition
What is 100.005 ? 0.095?
99.900
99.905
99.910
99.915
Subtract by converting to same decimal places: 100.005 ? 0.095. Thousandths: 5?5=0, hundredths: 0?9 (borrow) becomes 10?9=1, tenths: 9?0=9 after borrow, units: 99.910. Decimals Subtraction
What is 9.876 + 0.004?
9.879
9.880
9.884
9.890
Align decimals: 9.876 + 0.004. Add thousandths: 6+4=10 (carry 1), hundredths: 7+0+1=8, tenths and units stay same, giving 9.880. Decimals Addition
What is 15.2 ? 3.456?
11.744
11.745
11.754
11.746
Convert 15.2 to 15.200 and subtract 3.456. Subtract thousandths, hundredths, and tenths with proper borrowing to get 11.744. Always align decimals accurately. Decimals Subtraction
What is 23.789 + 15.006 ? 8.45?
30.235
30.345
30.355
30.445
First add 23.789 + 15.006 = 38.795. Then subtract 8.450 to match decimal places: 38.795 ? 8.450 = 30.345. Breaking into two steps and aligning decimals prevents mistakes. Decimals Guide

Cheat Sheet

  1. Align Decimal Points Precisely -

    When adding or subtracting decimals, always line up the decimal points vertically so digits occupy the correct place values, as recommended by Khan Academy. This alignment ensures you're adding tenths with tenths and hundredths with hundredths, avoiding misplacement errors.

  2. Use Trailing Zeros Strategically -

    Append zeros to the end of shorter decimals to create equal-length numbers without changing their value (e.g., 2.5 becomes 2.50), a tip endorsed by the National Council of Teachers of Mathematics. This trick simplifies column addition and subtraction, making mental checks more straightforward.

  3. Master the Borrowing Method -

    When subtracting decimals, if the digit in the minuend is smaller than the subtrahend, borrow from the next left column just like whole numbers, ensuring the decimal point stays fixed in place, following University of Cambridge guidelines. Practicing this cross-decimal borrowing prevents common subtraction mistakes.

  4. Estimate and Round for a Quick Check -

    Before finalizing your answer, round each decimal to the nearest whole number or tenth to estimate an approximate result - this quick mental check acts like a safety net to catch glaring errors, suggested by Harvard University Math Review. If your precise calculation deviates significantly, revisit your work for alignment or borrowing slip-ups.

  5. Apply Real-World Decimal Scenarios -

    Practice with everyday examples like money transactions or measurement conversions; this contextual learning reinforces decimal concepts and boosts recall, per the MIT Math Learning Center. Visualizing decimals in currency or metric units helps make abstract arithmetic more tangible and engaging.
