It is stipulated that "a" means the numerator and denominator of the fraction a, a number with a smaller value, such as "(2/3)"=2, "(19/17)"=17, "(1/2)*(6/7 )" = "(3/7)" = 3, according to this rule "(7/8)/(6/7)" = how much.
规定《a》表示分数a的分子、分母中数值小的一个数，如《(2/3)》=2，《(19/17)》=17，《(1/2)*(6/7)》=《(3/7)》=3，按这样的规定《(7/8)/(6/7)》=多少．
