Round 0.996 to two decimal places.

Round 0.996 to two decimal places.

• A. 1.00
• B. 0.99
• C. 1.01
• D. 0.996

Answer: (A)

Rounding to two decimal places uses the next digit (the thousandths place) to decide whether to bump the second decimal up. If that digit is 5 or more, you increase the hundredths digit by one; otherwise you leave it as is. For 0.996, the hundredths digit is 9 and the thousandths digit is 6, which is enough to trigger rounding up. Increasing the 9 by one carries over to produce 10 in the hundredths place, so the value becomes 1.00 when rounded to two decimals. The number is just under 1, but rounding up the hundredths with the carryover pushes it to 1.00. The other options either keep more digits than requested or would require a different rounding result than the rule dictates.
