0.45 if you are rounding to the nearest tenths.
0.495 if you are rounding to the nearest hundredths.
It's hard to tell if you are asking for the smallest hundredths decimal or if you are wanting to round to the nearest hundredths.
Five hundredths written as a decimal is 0.05 or .05.
.05
.05
0.05 or just .05 is five hundredths as a decimal.
.05? Me not sure...
In decimal form, 5 hundredths of a millimeter can be written in the form .05 mm.
.05 is 5 hundredths, or 50 thousandths etc or 5 percent
05 is the same as 5.0
5/100 = .05
In decimals: .05, in fractions: 5/100.
The .05 will round up, giving 22.1 as the answer.
If the point is your decimal, the zero in the tenths place and the five in the hundredths place, then "five hundredths" is all you need.
