Solution:

Consider the following expression:


(7)/(8)\text{ x }(4)/(5)

By definition, to perform this operation we must multiply numerator with numerator and denominator with denominator, as follows:


(7)/(8)\text{ x }(4)/(5)=\frac{7\text{ x 4}}{8\text{ x 5}}=(28)/(40)

that is:


(7)/(8)\text{ x }(4)/(5)=(28)/(40)

Simplifying, this is equivalent to:


(7)/(10)

So that, we can conclude that the correct answer is:


(7)/(10)
