Well, honey, it's all about fractions and making math easier for us mere mortals. The "tenth place" is where you stick the first decimal because it represents dividing something into ten equal parts. Starting with the "oneth place" would just confuse the heck out of everyone, so they kept it simple for our sake. You're welcome.
It needs to have decimals in order to round it to the nearest tenth ex:81.48 would be rounded to 81.5 because 4 is in the tenths place

The oneths place and the ones place would be the same thing. In the base ten system, the places are powers of ten. Hundreds is 102, tens is 101, ones is 100, tenths is 10-1, hundredths is 10-2. There is no room for a oneths place.

There isn't any. As you go to the right, each place is one tenth of the previous place.

A tenth of a number deals with decimals. The way to think about a tenth is that 1/10 is one tenth, and 1/10 as a decimal is 0.1. therefore the first decimal place is always the tenth of a number, so to answer your question the nearest tenth of 15.58 would be 15.6.
To find what 0.003 is one-tenth of in decimals, you can multiply 0.003 by 10. This gives you 0.03. Therefore, 0.003 is one-tenth of 0.03 in decimal form.
