Verified answer

Ответ:1) 1/2    2) 5/9   3) 1/6

Пошаговое объяснение:

1) 5/48 + 3/8 + 1/48 = 5+1/48 + 3/8 = 6/48 + 3/8 = 1/8 +3/8 = 4/8 = 1/2

2) (7/15+2/9) - 2/15 = 31/45 - 2/15 = 5/9

3) 14/27 - (5/27+1/6) = 14/27 - 19/54 = 1/6

Пошаговое объяснение:

5/48+3/8+1/48 = (5/48 + 1/48)+3/8 = 6/48+3/8 = 1/8+3/8 = 4/8 = 1/2=0.5.

(7/15+2/9)-2/15 = (7/15-2/15)+2/9 = 5/15 +2/9 =1/3+2/9 = 3/9+2/9 = 5/9.

14/27-(5/27+1/6) = (14/27-5/27) - 1/6 = 9/27 - 1/6 = 1/3 - 1/6 =  2/6 - 1/6= 1/6.
