Question

The two rational number a by B and C by D equal if

Answer 1

Step-by-step explanation:

Two such pairs, (a,b) and (c,d), are called equivalent (equal) if and only if ad=bc. This is an equivalence relation, being reflexive, symmetric and transitive, and so partitions the set of all such pairs into equivalence classes. A rational number is defined as an equivalence class of pairs.
