The number .8 is greater than .1. In decimal notation, the leftmost digit holds the highest place value, so in this case, the 8 in .8 is in the tenths place, while the 1 in .1 is in the hundredths place. Therefore, .8 is 8 tenths, which is greater than .1, which is 1 tenth.
There is no reason to suppose that it is. Nor, with over 8 decades of the century remaining, is it likely to be considered so.

8 times 10 years make 80 decades because 10 decades tines 8 decades will equal 80. (Hint:10 decades equals 1 year.)
