Round 7.6842 to the nearest hundredth.

• A. 7.69
• B. 7.60
• C. 7.68
• D. 7.67

Answer: (C)

Rounding to the nearest hundredth uses the thousandths place to decide if the hundredths digit goes up or stays the same. If the thousandths digit is 5 or more, you add 1 to the hundredths; otherwise you leave it as is. For 7.6842, the hundredths digit is 8 and the thousandths digit is 4. Since 4 is less than 5, we don’t increase the 8. The result is 7.68. The other options would require a thousandths digit of 5 or more to push the hundredths up, which isn’t the case here.
