помогите и пожалуйста нижний

Answer 1

(5,7 : 0,3 - 8 1/3) * 0,75
------------------------------   = 32,
  (2 1/8 + 1,75) : 15,5

1) 5,7 : 0,3 = 19,
2) 19 - 8 1/3 = 18 3/3 - 8 1/3 = 10 2/3,
3) 10 2/3 * 0,75 = 32/3 * 3/4 = 32/4 = 8,

4) 2 1/8 + 1,75 = 2 1/8 + 1 3/4 = 2 1/8 + 1 6/8 = 3 7/8,
5) 3 7/8 : 15,5 = 31/8 : 155/10 = 31/8 * 10/155 = 5/20 = 1/4,

6) 8 / (1/4) = 8 * 4 = 32
