A) 7/9
To simplify the prime factorization of the fraction 49/63, we can find the prime factorization of both the numerator (49) and the denominator (63) separately and then simplify.
Prime factorization of 49:
49 is equal to 7 * 7, so its prime factorization is 7^2.
Prime factorization of 63:
63 can be factored as 7 * 9, and further, 9 is 3 * 3. So, the prime factorization of 63 is 7 * 3 * 3.
Now, let's simplify the fraction:
49/63 = (7^2) / (7 * 3 * 3)
We can cancel out a common factor of 7 between the numerator and denominator:
49/63 = (7 * 7) / (7 * 3 * 3)
Now, cancel the common factor of 7:
49/63 = (7 * 7) / (7 * 3 * 3) = (7/7) * (7/3) * (1/3)
Now, you have a simplified fraction:
49/63 = (1) * (7/3) * (1/3)
Multiply the numerators and denominators:
49/63 = (7/9)
So, the simplified prime factorization of 49/63 is 7/9.
