Answer 1

1. 83/8=10 3/8 2. 31/6= 5 1/6

Answer 2

Пошаговое объяснение:

(х + 4 7/8) - 5 1/2 = 9 3/4

(х + 39/8) - 11/2 = 39/4

х = 39/4 - 39/8 + 11/2

х = (39*2-39+11*4)/8 = 83/8

=========================

(83/8 + 39/8) - 11/2 = 39/4

(83/8 + 39/8) - 44/8 = 78/8

78/8=78/8 или 39/4=39/4

7 11/12 + (6 3/10 - х) = 9 1/20

95/12 + (63/10 - х) = 181/20

х = 181/20 - 95/12 - 63/10

- х = (181*3 - 95*5 - 63*6)/60

- х= - 310/60

х = 310/60

==========================

95/12 + (63/10 - 310/60) = 181/20

475/60 + (378/60 -310/60 ) = 543/60

54360 = 543/60 или 181/20=181/20
