Решите уравнение. 1) 4/5 х = 8/15; 2) 7х = 3/8; 3) 3/11х = 9; 4) х : 1(13/14) = 1(17/18); 5) 2(5/8) : х = 1(19/20); 6)

1) 4/5 х = 8/15;х = 8/15 : 4/5;х = 8/15 * 5/4х = 2/3.

2) 7х = 3/8;х = 3/8 : 7;х = 3/8 * 1/7;х = 3/56.

3) 3/11х = 9;х = 9 : 3/11;х = 9 * 11/3;х = 33.

4) х : 1(13/14) = 1(17/18);х = 1(17/18) * 1(13/14);х = 35/18 * 27/14.х = 3(3/4).

5) 2(5/8) : х = 1(19/20); х = 2(5/8) : 1(19/20)х = 21/8 * 20/39;х = 1(9/26).

6) 1(8/9)х = 6,8;х = 6,8 : 1(8/9);х = 68/10 * 9/17;х = 3(3/5).
