What is 15 rounded to the nearest ten?

Answer

15 rounded to the nearest ten is
20

Nearest ten — the ones digit decides: 5⁠–⁠9 round up, 0⁠–⁠4 keep; digits to the right become 0.

Exactly halfway between 10 and 20 — equally close to both. The halfway rule rounds away from zero, as in school and Excel ROUND: 20. Round half to even (banker's rounding) gives 20.
