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:

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