Question

verify the closure property of addition of rational numbers ifa=3/8 and b=-5/7​

Answer 1

Step-by-step explanation:

The product of two rational numbers is always a rational number.

If a/b and c/d are any two rational numbers then (a/b × c/d) is also a rational number.

For example:

(i) Consider the rational numbers 1/2 and 5/7. Then,

(1/2 × 5/7) = (1 × 5)/(2 × 7) = 5/14, is a rational number
