Rational Numbers Examples In Real Life. If this approximation is adequate than you are able to represent the real world using rational numbers. Hence q is closed under multiplication.
It depends on what you call “real life”? 5/9 x 2/9 = 10/81 is a rational number. Motivation for mathematics, increased focus of a student, and plenty of examples for whole numbers, rational and real numbers can be made by using:
In maths, rational numbers are represented in p/q form where q is not equal to zero.
All numbers are rational except of complex and irrational (π,root of imperfect numbers). A friend of mine who was a carpenter needed to install a round ceiling light fixture and wanted to know how large a square hole could he cut in the ceiling so that the hole didn't extend beyond the rim of the fixture. It depends on what you call “real life”? If this approximation is adequate than you are able to represent the real world using rational numbers.
