Answer 1

Question:

Identify which expression is correct.

Solution:

By cross-multiplication notice that:

`(5)/(7)/\text{ }(3)/(7)=\text{ }\frac{5\text{ x 7}}{3\text{ x 7}}=\text{ }(5)/(3)\text{ x }(7)/(7)\text{ = }(5)/(3)\text{ x 1 = }(5)/(3)\text{ }`

then, the correct answer is :

`(5)/(7)/\text{ }(3)/(7)\text{ = }(5)/(3)\text{ }`
