Answer 1

(36/10 - 18/10* 11/3) : 4/10 = 

 

( 108/30 - 198/30 ) * 10/4 = 

 

-90/30 * 10/4  = 

 

-3 * 10/4 = -30/4 = -15/2 

 

 

 

( 76/100 ; 80/100 - 50/100 ) ; 55/100 = 

 

( 76/100 * 100/80 - 50/100 ) * 100/55 = 

 

( 7600/8000 - 50/100 ) * 100 / 55 = 

 

( 95/100 - 55/10 ) * 100/55 = 

 

40/100 * 100/55 = 

 

4000/5500 = 40/55 

 

 

(  (12 : 6/10) - (22/10 * 3/10) ) : 11/2 = 

 

(  ( 12/1 * 10/6) - ( 66/100) ) * 2/11 = 

 

 ( 120/6 - 66/100 ) * 2/11 = 

 

 ( 12000/600 - 396/600 ) * 2/11 = 

 

11604/600 * 2/11 = 23208/6600 = 967/275

Answer 2

(3,6-1,8*11/3);0,4=(3 3/5-1 4/5*11/3):2/5=(2 8/5-1 4/5*11/3):2/5=2 4/5*11/3):2/5=14/5*11/3):2/5=154/15:2/5=154/15*5/2=77/3=25 2/3

(0,76:4/5-0,5)*2=(0,76:0,8-0,5)*2=0,9

(12:3/5-11/5*0,3):11/2=(20-33/50):11/2=19 17/50:11/2=967/50*2/11=967/275
