Помогите сделать номер 358 и 361

Answer 1

358. 
 1) A= ab/6
2)  B= 27/4 · 56/45·xy = 27·14/45·xy = 378/45 ·xy = 8,4xy
3)  C = 13·4/3 ·dc = 52/3·cd = 17'1/3 ·cd
4)  55/3·13/11·9/13·abc = 15abc

361.
   1)    (1/2+1/3 - 1/4)·12/7 = (12+4 -3)/12 · 12/7 = 13/7 = 1'6/7
    2)    (4/7+5/21 - 2/3)·7/3 = (12+5 - 14)/21 ·7/3 = 3·/9 =1/9
    3)    (17/12 + 43/18 - 11/9)·48/31 = (51+86 - 44)/36 · 48/31 = 
                    = 93/3 · 4/31 = 4
