There is no such thing as ones in decimals, so I am assuming you mean tenths. If you were to round this to the tenths place, the answer would be 13.6.
13.555 → 13.6 (4 and below, leave it alone. 5 and up, round it up)\
Hope this helps!
Answer:
13.6
Explanation:
Since it is asking for 1 decimal place, we assume that it is the tenths decimal place. Since the hundredths decimal place is ≥5, we round up to 6.
