A) 3 i 1/4 * 5 = 13/4 * 5= 65/4 = 16 i 1/4 = 16,25
B) 1i 3/25 * 10= 28/25 * 10 = 280/25= 11 i 5/25 = 11,2
C) 12* 5 i 8/16= 12 * 88/16= 1056 /16 =66
D) 9* 1 i 5/12= 9 * 17/12 = 153/12 = 12,75
E) 4 i 5/6 :3 = 29/6 :3/1= 29/6* 1/3 =29/18 = 1 i 11/18
F) 2 i 5/12 : 4= 29/12:4= 29/12 : 4/1 = 29/12 * 1/4= 29/48
G) 3 i 1/15:6= 46/15 :6= 46/15 : 6/1 = 46/15* 1/6= 46/ 90= 23/45
H) 1 i 3/16 :10 = 19/16 :10 = 19/16 : 10/1= 19/16 * 1/10= 19/160
myślę, że pomogłem ;p
