The answer is 192 / 59, which is 15 / 3 of 59
Solution: the original column numbers are 48 / 1424, 48 / 672, 48 / 316, 48 / 148, 48 / 69, 48 / 32, ()
Analysis: 32 * 2 + 5 = 69, 69 * 2 + 10 = 148148 * 2 + 20 = 316316 * 2 + 40 = 672672 * 2 + 80 = 1424, so the next denominator should be 2 times of a number + half of 5 = 32, the reverse operation, (32-2.5) / 2 = 14.75, the last denominator should be 14.75, that is, the score is 48 / 14.75, the number into the simplest score is 192 / 59
