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.
Well, isn't that a happy little question! Decimals start with the tenth place because they represent parts of a whole, like a pie or a painting. Just like how a whole number represents a complete object, decimals show us smaller parts of that whole. So, starting with the tenth place helps us understand and appreciate those smaller pieces a little better.
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
Decimals are tenth parts. E.g. one tenth of a metre can be written with a decimal: 0.1 m.
1/10 = 0.1

.1 tenth .01 hundredth .001 thousandth .0001 ten-thousandth .00001 hundred- thousandth .000001 millionth so on and so forth
Decimals start with the tenth place because they are a way to represent numbers that fall between whole numbers. The decimal point separates the whole number part from the fractional part, with each place value to the right of the decimal point representing a power of 10. The first place to the right of the decimal point is the tenths place because it represents one-tenth of a whole unit. This system allows for precise and flexible representation of values between whole numbers.

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.
