What is 56.98 rounded to the nearest tenth?

• A. 57.0
• B. 56.9
• C. 56.98
• D. 57

Answer: (A)

Rounding to the nearest tenth means you keep one digit after the decimal point and look at the next digit to decide whether to round up. In 56.98, the tenths place is 9 and the hundredths place is 8. Since the hundredths digit is 8 (which is 5 or more), you round the tenths digit up by 1. Increasing 9 by 1 carries into the whole number part, turning 56 into 57 and leaving the decimal as .0. So, 56.98 rounds to 57.0 to the nearest tenth. Note that rounding to a whole number would give 57, but the instruction asks for the nearest tenth, so 57.0 is the correct form.
