Answer 1

a) 5 i 2/5 : 5 i 2/5 =
= 27/5 : 27/5 =
= 27/5 * 5/27 =
= 1
======================
b) 3 i 1/22 * 11/3 =
= 67/22 * 11/3 =
= 67/6 =
= 11 i 1/6
======================
c) (1/2 + 1/5) : 1/2 =
= (5/10 + 2/10) : 1/2 =
= 7/10 : 1/2 =
= 7/10 * 2 =
= 7/5 =
= 1 i 2/5
==============================
d) (11 i 1/2 - 10 i 1/2) :  2 i 5/6 =
= 1 : 17/6 =
= 1 * 6/17 =
= 6/17
=========================
e) (3/8 + 1/3) : (3/4 + 0,5) =
= (9/24 + 8/24) : (3/4 + 2/4) =
= 17/24 : 5/4 =
= 17/24 * 4/5 =
= 17/30
==============================
f) (2 i 3/4 + 0,5) : (7,2 - 1/3) =
= (11/4 + 2/4) : (7 i 1/5 - 1/3) =
= 13/4 : (36/5 - 1/3) =
= 13/4 : (108/15 - 5/15) =
= 13/4 : 103/15 =
= 13/4 * 15/103 =
= 195/412
==============================
g) (1/3 * 6/5 - 6/5) : 1/3 =
= 1 * 2/5 - 6/5) : 1/3 =
= (2/5 - 6/5) : 1/3 =

= -4/5 * 3 =
= -12/5 =
= -2 i 2/5
===============================
h) 1/2 - 1/2 : (4 i 3/4 - 3/4) =

= 1/2 - 1/2 : 4 =
= 1/2 - 1/2 * 1/4 =
= 1/2 - 1/8 =
= 4/8 - 1/8 =
= 3/8
=========================================================
j) (1 i 3/4 : 2/3) - 1,75 - 1 i 1/8 : 3/32 | 1 i 1/4 -(-1/2)² * 3 =
= (7/4 * 3/2) - 1 i 3/4 - 1 i 1/8 * 32/3 | 5/4 - 1/4 * 3 =
= 21/8 - 7/4 - 9/8 * 32/3 | 1 * 3 =
= 21/8 - 14/8 - 12 | 3 =
= 7/8 - 12 | 3 =
= 7/8 - 11 i 8/8 | 3 =
= 7/8 - 96/8 | 3 =
= -89/8 | 3 =
= -89/8 : 3 =
= -89/8 * 1/3 =
= -89/24 =
= -3 i 17/24
