Four hundred nine and one-tenth as a decimal?

Answer 1

Any number is converted to a decimal by writing the integer part on the left side of the decimal point and the fractional part on the right side of the decimal point. The first place on the left side of the decimal point is called the ten's. After that, we have the hundred's, thousand's, ten-thousands, etc. On the right hand side of the decimal point, we have the tenth's, hundredth's, thousandth's, ten thousandth's, etc. So four hundred nine and one-tenth is 409.1.
