Tenths are a way to easily write fractional numbers without having to use fractions.

For example, a ruler with tenths, if you have 7/10ths you would write it as 0.7

If you have a regular ruler and it is 7/16ths, that is 0.4375 in decimal.

Plus, adding tenths is easier.  Add 4.3 and 9.1 is easy, while adding 3 3/4th and 7 9/16ths is more difficult.
