Keisha's teacher gives her the following information: • m, n, p, and q are all integers and p = 0 and q + 0
• A= " and B =
What conclusion can Keisha make?
A - B =
mp + ng
P9
so the product of two rational numbers is a rational number.
A+B=
mp + ng
, so the sum of two rational numbers is a rational number.
P9
AB=
mp + ng
pg
