Decimal place value

The first digit after the decimal represents the tenths place. The next digit after the decimal represents the hundredths place. The remaining digits continue to fill in the place values until there are no digits left.
Example: 0.810.81
The number 0.810.\blueD8\greenD1 is made up of 8\blueD8 tenths and 1\greenD1 hundredth.
We can also write this as:
0.81=0.8+0.010.\blueD8\greenD1=\blueD{0.8}+\greenD{0.01}
or
0.81=810+11000.\blueD8\greenD1=\blueD{\dfrac8{10}}+\greenD{\dfrac1{100}}
Or we can use a place value chart:
Ones.TenthsHundredths
00..8\blueD81\greenD1
