Answer 1

(x+4 7/8)-5 1/2=9 3/4

x + 4 7/8 = 9 3/4 + 5 1/2

x + 4 7/8 = 9 3/4 + 5 2/4

x + 4 7/8 = 14 5/4

x = 14 5/4 - 4 7/8

x = 14 10/8 - 4 7/8

x = 10 3/8

11/12 + (6 3/10 - x) = 9 1/20

6 3/10 - x = 9 1/20 - 7 11/12 =>

HOK(20;12)=60=>

6 3/10 - x = 9 3/60 - 7 55/60 ;

6 3/10 - x=8 63/60-7 55/60;

6 3/10 - x = 1 8/60 = 1 2/15 ;

x=6 3/10-1 2/15 HOK(10; 15) = 30

x = 6 9/30 - 1 4/30 ;

x = 5 5/30 = 5 1/6
