Question

Oblicz :

(1/2)+(15 1/3-(2*1 1/2)

1 3/7:10-4 1/2*2

8 5/8*2:4 1/6

(2 1/3-1 1/2)

Answer 1

(1/2)+(15 1/3-(2*1 1/2) =  1/2 + (15 1/3 - 3) = 3/6 + 12 2/6 = 12 5/6
1 3/7 : 10 - 4 1/2 * 2 = 1/7 - 9 = (- 8 6/7)
8 5/8 * 2 : 4 1/6 = 17 1/4 : 4 1/6 = 4 7/50
(2 1/3-1 1/2) = 2 2/6 - 1 3/6 = 1 8/6 - 1 3/6 =5/6
