Round the number 2,876 to the nearest ten.

• A. 2,860
• B. 2,870
• C. 2,880
• D. 2,890

Answer: (C)

Rounding to the nearest ten means making the number a multiple of ten by looking at the ones digit. If the ones digit is 5 or more, you increase the tens place by 1; if it’s 0–4, you keep the tens place the same and set the ones to 0. In 2,876, the ones digit is 6, which is 5 or more, so you bump the tens place from 7 to 8 and set the ones to 0. That gives 2,880. It's closer to 2,880 than to 2,870 or 2,860, since 2,876 is 4 away from 2,880 and farther from the other options, and the same rule applies in general: 5–9 rounds up, 0–4 rounds down.
