Answer 1

44 1/5-[5*(0,8+1,6)-2,2]=44 1/5-[5*2,4-2,2]=44,2-[12-2,2]=44,2-9,8=34,4

 

[6-(1,5*2 1/4+2,75*4/11)]:3 1/4= [6-(1 1/2*2 1/4+2 3/4* 4/11)]: 3 1/4=[6- ( 3/2* 9/4 + 11/4 *4/11)] :13/4= [6-(27/8+1)]:13/4=[6-(3 3/8+1)] * 4/13=(6-4 3/8)* 4/13= 1 5/8 * 4/12=13/8*4/13= 1/2

 

x= 1 3/4*0,5/ 1+ 3/4*0,5=7/4*1/2/1+3/4*1/2=7/8/1+3/8=7/8:11/8=7/8*8/11=7/11

 

y=1-1/2*0,6/1+ 1/4*1,6=1-1/2*3/5/1+1/4*1 3/5=1-3/10/1+1/4*8/5=7/10:(1+2/5)=7/10:1 2/5= 7/10*5/7=1/2
