A) x * 5/6 = 15/28. 

Х = 15/28 : 5/6 = 15/28 * 6/5 = 3/14 * 3 = 9/14.

в) 26/27 * x = 13/54. 

Х = 13/54 : 26/27 = 13/54 * 27/26 = 1/2 * 1/2 = 1/4.

д) x : 3/7 = 14/15. 

Х = 3/7 * 14/15 = 1 * 2/3 = 2/3.

б) 7/9 : x = 7/18.

Х = 7/9 : 7/18 = 7/9 * 18/7 = 2.

г) x + 3/7 = 1.

Х= 1 - 3/7 = 4/7.

е) x - 5/16 = 1/4. 

Х = 5/16 + 1/4 = 5/16 + 4/16 = 9/16.

а) 3 : 5 = 3/5.

б) 12 : 15 = 12/15 = 4/5.

в) 1/2 : 8 = 1/2 * 1/8 = 1/16.

г) 8 : 1/2 = 8 * 2 = 16.

д) 5 : 5 = 1.

а) 1 - 1/8 : 6 = 1 - 1/48 = 47/48.

б) 1 - 7/15 : 5 = 1 - 7/15 * 1/5 = 1 - 7/75 = 68/75.

в) 1 - 3/10 : 2 = 1 - 3/20 = 17/20.
