Decimal Numbers

Numbers that lie between integers on the number line can be written as decimal numbers. Decimal numbers consist of an integer part, a decimal point as a separator, and a non-zero decimal part written to the right of the decimal point. Consider the decimal number 12.346.

The integer part of this number is 12. Since there is a decimal part, 0.346, the number is greater than 12 but less than 13. Therefore, when plotting 12.346 on a number line, the point will lie between 12 and 13.
