Question

using commutativity and associativity of addition of rational number , express each of the following as a rational:

3/ 7 + - 4 / 9 + - 11 / 7 + 7/9​

Answer 1

So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication. Thus, multiplying two rational numbers produces another rational number.So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication.
