1) 25/27х=9/14
350 = 243х
х=350/243
х=1,44 или 1 107/243
2) 13/17х=39
663х=13
х=13/663
3) 4х=5/7
28х=5
х=5/28
4) х / ( 2 2/15)=1 9/16
х / (32/15) = 25/9
х= (32/15) * (25/9)
х = 160/27= 5 25/27
5) 4 4/9 /х = 6/35
40/9 / х = 6/35
х = (40/9) * (35/6)
х= 700/27= 25 25/27
6) 3/8х = 5,2
41,6х = 5,2
х = 5,2 / 41,6
х= 0,125
