Keisha's teacher gives her the following information: m, n, p, and g are all integers and pneq 0 and qneq 0 A= m/q and B= n/p What conclusion can Keisha make? A、 B= mp+nq/pq , so the product of two irrational numbers is an irrational number. A . B= mp+nq/pq , so the product of two rational numbers is a rational number.. A+B= mp+nq/pq , so the sum of a rational number and an irrational number is an irrational number. A+B= mp+ng/pq , so the sum of two rational numbers is a rational number.
