(1 i 1/5 - 0,5) * 3 i 1/3 = (1 i 1/5 - 5/10) * 3 i 1/3 = (1 i 2/10 - 5/10) * 3 i 1/3 = (12/10 - 5/10) * 3 i 1/3 = 7/10 * 10/3 = 7/3 = 2 i 1/3
3/4 + 0,75 * 1 i 1/3 = 3/4 + 0,75 * 4/3 = 3/4 + 3/4 * 4/3 = 3/4 + 1 = 1 i 3/4
3,7 - 1,2 : 1/2 = 3,7 - 12/10 * 2/1 = 3,7 - 12/5 = 3,7 - 2,4 = 1,3
(5,6 - 3,1) : 3 i 1/2 = 2,5 : 7/2 = 25/10 * 2/7 = 25/35 = 5/7
2/7 + 7/9 * 2,7 = 2/7 + 7/9 * 27/10 = 2/7 + 21/10 = 20/70 + 147/70 = 167/70 = 2 i 27/70
3,2 - (1,9 : 5/8) = 3,2 - (1,9 : 0,625) = 3,2 - 3,04 = 0,16
(1/2)² : 8 * 4 = 1/4 * 1/8 * 4 = 1/32 * 4 = 1/8
