Вычислить: 4,8(2 целых 1/3-3 цел.3/8)+12 цел,4/9

   (2 1/3 - 3 3/8) * 4 4/5 + 2 4/9 = (7/3 - 27/8) * 24/5 + 2 4/9 = 
= (56/24 - 81/24) * 24/5 + 2 4/9 = -25/24 * 24/5 + 2 4/9 =
= -5 + 2 4/9 = -2 5/9;

1) 2 1/3 - 3 3/8 = 7/3 - 27/8 = 56/24 - 81/24 = - 25/24
2) - 25/24 * 24/5 = - 5
3) - 5 + 2 4/9 = -2 5/9
