ответ - 5/8  кароче сначала делим -9/16 на 3/8 переворачиваем вторую дробь, т.е 3/8 получаем 8/3 , сокращаем, получаем -3/2 , выделяем целую часть получаем минус одну целую , одну вторую (-1.1/2) далее вычитаем из 1  -1.1/2 получаем -1/2 и приводим ее к общему знаменателю с дробью 1/8 ( домножаем 1/2 на 4) получаем -4/8 -1/8 = -5/8 ( но все это действительно если я правильно поняла и / означает дробную черту)
