Answer 1

(15:3 3/4-(-10 1/2 :1 1/2)·3/14):(1 1/4- 1 23/52)=
=(5 3/4+10 1/2* 3/14):(1 13/52- 1 23/52)=
=(5 3/4+ 10 3/28):(-1 10/52)=
=(5 21/28 +10 3/28) : (-1 10/52)=
=15 24/28 :(-1 10/52)=

(15:3 3/4-(-10 1/2 :1 1/2)·3/14):(1 1/4- 1 23/52)=
=(5 3/4+10 1/2)* 3/14):(1 13/52- 1 23/52)=
=(5 3/4 +10 2/4)*3/14:(-1 10/52)=
=16 1/4*3/14:(-1 10/52)=
=
