Suppose multiplication over rationals was defined as follows:


“ For any two rationals a//b and c//d where a, b, c, d not equal to 0 ∈ Z, the product is given by a//b × c//d = ad//bc ”


Explain what goes wrong here and how does this definition restrict us in further developing the calculus of rationals. Provide sound mathematical reasoning to support your explanation.

Suppose multiplication over rationals was defined as follows:
" For any two rationals a//b and c//d where a, b, c, d # 0 E Z, the product is given by
a//b x c//d = ad//bc
Explain what goes wrong here and how does this definition restrict us in further developing the calculus
of rationals. Provide sound mathematical reasoning to support your explanation.
