Answer 1

i) (1 i 3/5 + 2 i 1/5) : 6 i 1/3 = 3 i 4/5  : 6 i 1/3= dziewiętnaście piątych (19/5) *3/19 = trzy piąte

j)(3 i 8/14 + 11/14)*3 i 1/5)= 3 i 19/14 * 3 1/5 =  13 i 33/35

 

k)1 i 1/4  : 1/4 - 3 i  2/3 = 5/4 : 1/4 - 11/3 =5/4 * 4/1 -11/3 = 5/ - 11/3 = 15/3 - 11/3 = 4/3

 

l) 1- 1/8 - 5/6

____________       =24/24 - 3/24 - 15/24
