Answer 2

9 3/8:(1 1/2)do potegi 3 -1 5/6= 75/8 : (3/2) do potęgi 3 - 11/6 = 75/8 : 27/8 - 11/6 = 75/8 * 8/27 - 11/6 =  75/27 - 11/6 = 25/9 - 11/6 = 50/18 - 33/18 = 17/18

0,26:(6,35-4 2/5)= 26/100 : (6,35 - 4,4) = 26/100 : 1,95 = 26/100 : 195/100 = 26/100 * 100/195 = 26/195 = 2/15

(1 3/5+2,2):6 1/3= (1,6 + 2,2) : 19/3 = 3,8 : 19/3 = 38/10 * 3/19 = 2/30 = 1/15

(3 4/7+11/14)*3,2= (25/7+11/14)*3,2 = (50/14 + 11/14) * 3,2 = 61/14 * 3,2 = 61/14 * 32/10 = 488/35 = 13 33/35

1 1/4 : 0,25- 3 2/3= 1,25 : 0,25 - 3 2/3 = 5 - 3 2/3 = 1 1/3
