Answer 1

a) (1/2) +1 cala i 1/2 :3/4 =1/2 + 3/2  x 4/3 = 1/2 + 2 = 2 i 1/2

 

b)5/7 x 1 cala i 3/4 -  (1/2)=5/7 x 7/4 = 5/4 = 1 i 1/4

 

c)(1/3) x 1 cala i 1/8 +1 cala i 1/2 =  1/3 x 9/8 + 1 i 1/2 = 3/8 + 1 i 4/8 = 1 i 7/8

Answer 2

a) (1/2) +1 cala i 1/2 :3/4 =1/2 + 3/2  x 4/3 = 1/2 + 2 = 2 i 1/2

b)5/7 x 1 cala i 3/4 -  (1/2)=5/7 x 7/4 = 5/4 = 1 i 1/4

c)(1/3) x 1 cala i 1/8 +1 cala i 1/2 =  1/3 x 9/8 + 1 i 1/2 = 3/8 + 1 i 4/8 = 1 i 7/8 Prosze
