2008 / 2007 numerator minus a number, denominator plus this number, the score is 2 / 3, what is the number
If you subtract a number from the numerator of 2007 in 2008 and add this number to the denominator, the sum of numerator and denominator will remain unchanged, or will 2008 + 2007 = 4015 reduce the score to 2 / 3, the sum of numerator and denominator to 54015 △ 5 = 803, 2x803 = 1606, 3x803 = 2409, so the score before reducing the score to 1606 / 24092007-1606
