Can a rational number be a decimal
WebIt is a rational number. In general, any decimal that ends after a number of digits such as [latex]7.3[/latex] or [latex]-1.2684[/latex] is a rational number. We can use the place value of the last digit as the denominator when writing the decimal as a fraction. WebAny real number can be approximated to any desired degree of accuracy by rational numbers with finite decimal representations. Assume x ≥ 0 {\displaystyle x\geq 0} . Then for every integer n ≥ 1 {\displaystyle n\geq 1} there is a finite decimal r n = a 0 . a 1 a 2 ⋯ a n {\displaystyle r_{n}=a_{0}.a_{1}a_{2}\cdots a_{n}} such that:
