Question

There are two rational numbers a and b such that a+b=7, when we divide ‘a’ by ‘b’, the closure property of the rational numbers does not hold true. What will be the value of (a-b) and (a×b).

The closure property states that for any tworational numbers a and b, a ÷ b is also arational number. The result is a rational number. … So rational numbers are not closed under division. But if we exclude 0, then all therational numbers are closed under division.
