Answer 1

a) 2/3 + 1/6 * 3/4 = ⁸⁾2/3 + 3/24 = 16/24 + 3/24 = 19/24
d) 11 si 1/2 - 4 * 2 si 1/4 = 23/2 - 4 * 9/4 = ²⁾23/2 - 36/4 = 46/4 - 36/4 = 10/4 =           5/2 = 2 si 1/2
g) 1 si 1/6 + 1/10 * (1 si 1/3 - 1/2) = 7/6 + 1/10 * (²⁾4/3 - ³⁾1/2) = 7/6 + 1/10 * (8/6       - 3/6) = 7/6 + 1/10 * 5/6 = ¹⁰⁾7/6 + 5/60 = 70/60  + 5/60 = 75/60 = 1 si 15/60         = 1 si 1/4
