Answer 1

(36 : 21/50 - 75 3/14) : 3 =
= (36 * 50/21 - 1053/14) : 3 =
= ( 600/7 - 1053/14) : 3 = 
= (1200/14 - 1053/14) : 3 =
=  147/14 * 1/3 = 
=  49/14 =
= 3 7/14 = 
= 3 1/2

Answer 2

7,5*4+5 1/4:14                        30 + 21/4 * 1/14                           30 + 3/8

------------------------------ = ----------------------------------- = --------------------------- =

(36: 21/50 - 75 3/14):3        (36 * 50/21 - 75 3/14) : 3         (600/7 - 75 i 3/14):3

 

   30 i 3/8                                          30 i 3/8                        30 i 3/8

------------------------------- =  ------------------------------- = -----------------------=

(85 i 5/7  - 75 i 3/14) : 3       (85 - 10/14 - 75 i 3/14):3       10 i 7/14 : 3

 

 

30 i 3/8 :( 10 i 1/2 : 3) = 30 i 3/8 : (21/2 * 1/3) = 30 i 3/8 : 7/2 = 243/8 * 2/7 = 243/28 = 8 i 19/28
