$\frac{12}{13}$
To simplify a fraction, we find the GCF (Greatest Common Factor) of the numerator and denominator. Then, we divide the numerator and denominator by that number. The factors of 48 are {1, 2, 3, 4, 6, 8, 12, 16, 24, 48}, and the factors of 52 are {1, 2, 4, 13, 26, 52}. The greatest common number in those sets is 4. We divide the numerator and denominator of the fraction by 4 to get $\frac{48}{52}=\frac{12}{13}$
