    What is 0.45 rounded to the nearest tenth?

    Answer

    0.45 rounded to the nearest tenth is
    0.5

    Nearest tenth — 1 decimal place. The hundredths digit decides: 5⁠–⁠9 round up, 0⁠–⁠4 keep.

    Exactly halfway between 0.4 and 0.5 — equally close to both. The halfway rule rounds away from zero, as in school and Excel ROUND: 0.5. Round half to even (banker's rounding) gives 0.4.
