Hello!The answer is:  Multiply the numerators, multiply the denominators, and then simplify. Why? Let's discard each given option in order to find the correct one.First option,Find a common denominator for the two fractions: Incorrect, there Mrs. Cho does not need to find a common denominator since it's a fraction multiplication. We find common denominators when we are doing additions or subtractions of fractions.Second Option,Divide the numerator and denominator of the first fraction by x2 and y: Incorrect, Mrs. Cho does not need to divide the numerator and denominator of the first fraction by x2 and y, doing that would not help at all, it's a useless step.Third Option,Multiply the numerators, multiply the denominators, and then simplify: Correct, Mrs. Cho should multiply and then, simplify the result:As we can see,the fraction is simplified because the first fraction numerator and the second fraction denominator are equal.Fourth Option,Multiply the first fraction by the reciprocal of the second fraction:Incorrect, Mrs. Cho does not need to multiply the first fraction by the reciprocal of the second fraction since it's not a fraction division.Have a nice day!...
