When rounding to the nearest tenth, we need to look at the hundredths place to determine if the tenths place stays the same or increases by one.
The number 28.37 has a 3 in the tenths place and a 7 in the hundredths place. Since the hundredths place is 5 or larger (in this case, 7), we round up the tenths place by one.
So, 28.37 rounded to the nearest tenth is:
28.4
