Answer 2

Ответ:1 1/5 = 1.2.

Пошаговое объяснение:

1 1/48 * 2 2/5 - (9 1/6 * 4/15 + 2 5/9) * 1/4=1 1/5 = 1.2.

1)  9 1/6 * 4/15=(9*6+1)/6 * 4/15 = 55/6*4/15=(55*4)/(6*15)=22/9=2 4/9;

2)  2 4/9 + 2 5/9 = 4 9/9 = 5;

3)  5*1/4=5/4=1 1/4;

4)  1 1/48 - 2 2/5=49/48 * 12/5 = (49*12)/(48*5)=49/20=2 9/20;

5)  2 9/20 - 1 1/4 = 2 9/20 - 1 5/20 = 1 4/20 = 1 1/5 = 1.2.
