Answer 1

Д) (1/2 + 1/3) * 2 = (3/6 + 2/3) * 2 = 5/6 *2 = 5/3 = 1 2/3
-----------------------------------
е) (1/2 - 1/3) *3 = (3/6 - 2/6) * 3 = 1/6 * 3 = 1/2
----------------------------------
д)(1/4 + 1/6) : 10 = (3/12 + 2/12) : 10 = 5/12 : 10 = 1/24

Answer 2

(1\2+1\3)*2 = (3\6+2\6)*2 = 5\6*2 = 10\6 = 5\3 = 1 2\3
(1\2-1\3)*3 = (3\6-2\6)*3 = 1\6*3 = 1\2
