4 4/27-x=1 8/9 , x+2,25=6 4/9-2 1/2 , 6 2/3-(x+0,25)=2 1/6

Question

4 4/27-x=1 8/9 , x+2,25=6 4/9-2 1/2 , 6 2/3-(x+0,25)=2 1/6

Answer 1

4 4/27-х=1 8/9
х= 4 4/27 - 1 24/27
х=3 31/27-1 24/27
х=2 7/27

х+2,25=6 4/9 - 2 1/2
х+2,25= 6 8/18 - 2 9/18=5 26/18-2 9/18
х+2,25= 3 17/18
х=3 17/18-2 1/4=3 34/36 - 2 9/36 = 1 25/36

6 2/3-(х+0,25)=2 1/6
Х+0,25=6 4/6-2 1/6=4 3/6=4 1/2=4,5
Х=4,5-0,25=4,25
