Answer 1

a) 1/2 do pot. 3 + 1  1/2 : 3/4 = 1/8 + 1 1/2 : 3/4 = 1/8 + 3/2 x 4/3 = 1/8 + 2/1 = 

    = 1/8 + 2 = 2  1/8

b) 5/7 x 1  3/4 - 1/2 do pot. 2 = 5/7 x 1  3/4 - 1/4 = 5/7 x 7/4 - 1/4 = 5/4 - 1/4 = 

    = 4/4 = 1

c) 1/3 do pot. 2 x 1  1/8 + 1  1/2 = 1/9 x 9/8 + 1  1/2 = 1/8 + 1  1/2 = 1/8 + 1  4/8 =   

    = 1  5/8
