How do I round to the nearest tenth?
Direct answer
Look at the hundredths digit (second after the decimal). If it is 5 or greater, round the tenths digit up; if 0–4, keep the tenths digit. Featured homework answer: 36.89753 → 36.9.

Honest limit: some courses teach banker’s rounding for exact 5s; this guide uses the common school rule (5 rounds away from zero / up for positives).
