Round decimals.
Round the numbers.

🙂 = Correct, ☹️ = Incorrect

📌 Rules

• Identify the target place value: Find the digit in the place you are rounding to (e.g. whole number/ones, tenths, or hundredths).

• Look at the decider digit (the digit to the right): Check the next digit directly to the right of your target place.

– If the decider digit is 5, 6, 7, 8, or 9, round up (add 1 to the target digit).

– If the decider digit is 0, 1, 2, 3, or 4, round down (keep the target digit the same).

💡 Tips

• Examples of rounding:

– Rounding 3.74 to the nearest whole number: decider digit is 7, so round up to 4.

– Rounding 5.283 to 1 decimal place (tenths): decider digit is 8, so round up to 5.3.

– Rounding 8.142 to 2 decimal places (hundredths): decider digit is 2, so round down to 8.14.

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Just type plain digits or decimals like 4, 5.3, or 8.14 without adding any spaces or extra words.

⚠️ Warnings

• Drop digits after the target place: Do not leave trailing digits after the place value you rounded to! For example, rounding 4.37 to 1 decimal place gives 4.4, not 4.40 or 4.47.

• Watch out for 9 rolling over: If you need to round up a 9 (e.g. rounding 2.96 to 1 decimal place), the 9 becomes 0 and carries 1 to the column on the left, giving 3.0.
