Question

выполните деление: -6:3/7;. 1:8/19; -7/25:(-28); -16 1/3: (-5 5/6); 2 2/3:2 2/7; 4 4/9: -(-5/27).​

Answer 1

Ответ:

-6:3/7 = -6 * 7/3 = -42/3 = -14;  

1:8/19 = 1* 19/8 = 2  3/8;

-7/25 : (-28) = -25/7 * (-28) = -7 * (-4) = 28;

-16 1/3 : (-5 5/6) = -49/3 * (- 6/35) = 98/35 = 14/5 = 2 4/5;

2 2/3 : 2/7 = 8/3 * 7/2 = 28/3 = 9  1/3;

4 4/9 : (-5/27) = 40/9 * (-27/5) = -12/5 = -2 2/5
