Final answer:
Tripling both x and y in the fraction XZ/YA does not change the value of the fraction; it remains the same.
Step-by-step explanation:
To determine how the value of the fraction changes when x and y in the fraction XZ/YA are both tripled, we can represent the new fraction as (3x)Z/(3y)A. Since both x and y are tripled, we can factor out the common '3' to simplify the expression, effectively cancelling out the '3' in the numerator and denominator. Therefore, we have the simplified fraction as XZ/YA, which is the same as the initial fraction before tripling x and y.
This means the value of the fraction remains the same even after x and y both are tripled. The answer to the student's question is that the value of the fraction E. remains the same.
