Decimal numbers are numbers which contain a integral part before a point and a decimal part after the point. The first step in solving decimal arithmetic is being able to understand decimal numbers. Reading a decimal number is similar to reading a whole number except for a few minor differences. In a normal number the right most digit is ones place and the place next to it is tens place and so on the value of the position increases as you move left. But a decimal number starts from a tenths place and decreases according as you move from left to right. In his way the place values are called as tenths, hundredths, thousandths etc., Note that there is no ones place in the decimal part. This video shows how to read decimals numbers.
