What is 6.75 minus 2.4?

• A. 3.35
• B. 4.35
• C. 4.75
• D. 6.75

Answer: (B)

When subtracting decimals, line up the decimal points so each place value (ones, tenths, hundredths) is in its own column. Treat 2.4 as 2.40 so the hundredths place lines up with 6.75. Subtract column by column: - hundredths: 5 − 0 = 5 - tenths: 7 − 4 = 3 - ones: 6 − 2 = 4 Reading the result gives 4.35. So the difference is 4.35. This also matches the quick check: 6.75 is about 6.8, and 2.4 is about 2.4, so the result should be a little over 4.3, which 4.35 confirms. If you see other numbers like 4.75 or 3.35 coming up, those would come from subtracting different amounts (like subtracting 2.0 or 3.40), not from subtracting 2.4 from 6.75.
