How do you decide if a decimal is a rational number? - Answers

A rational number is one which can be expressed as one integer over another.A decimal is a rational number if:It terminates; orit ends with a repeating (cycle of) digit(s)eg 0.5, 0.333...., 0.181818..., 0.1666... are all rational numbers which can be expressed as one integer over another:0.5 = 1/20.333... = 1/30.181818... = 2/110.1666... =1/6Any number which is not rational is an irrational number; its decimal representation does not terminate nor does it end with a repeating (cycle of) digit(s).eg 0.1234567891011121314... (the counting numbers strung together after a decimal point)π = 3.1415926535897932... (the ratio of the circumference to the diameter of a circle)e = 2.71828218284590452... (Euler's number, the base of natural logarithms)√2 = 1.414213562373095...are all Irrational Numbers
