We will consider here the general properties such as associative, commutative, distributive and closure properties, which are also defined for integers. ➢ Evaluate a variety of arithmetic computations involving rational numbers and solve problems as they relate to the workforce.We study the closure property for the four basic operations that is addition subtraction multiplication and division. Verify closure property and commutative property of addition for each pair of the given rational rumber. There exist sequences of rational numbers that converge to irrational numbers, so the rational numbers are not closed. Closure property for rational numbers under then operations of addition, subtraction, multiplication and division. Closure property of rational numbers under addition: The sum of any two rational numbers will always be a rational number, i.e. Closure property for rational numbers under then operations of addition, subtraction, multiplication and division. This paper demonstrates that it is not intrinsically at odds with rational behavior. Cut out each of the figures provided at the end of the lesson. 1.
