Пошаговое объяснение:
а) 4 3/4 +x = 16 7/8
4 6/8 +x = 16 7/8 ; x = 12 1/8 = 12.125
б) 0.125*1/4 = 1/2 - x ; 1/8 * 1/4 = 1/2 - x ; 1/32 = 16/32 - x ; x = 15/32
в) 7/8 + x = 5 * ( 5/6 - 3/5 )
7/8 + x = 5 * ( 25/30 - 18 / 30 ) ;
7/8 + x = 5 * 7/30 ;
7/8 + x = 7/6 ;
42 / 48 + x = 56 / 48 ;
x = 14/48 = 7/24

х= 16 7/8 - 4 6/8
х= 12 1/8
в) 1) 5/6-3/5 = 25/30-18/30= 7/30
2. 5*7/30= 7/6
7/8+х=7/6
х=7/6-7/8
х=28/24-21/24
х=7/24
