b) 1/5 - 0,01 : 0,2 = 20/100-1/100:2/10= 19/100x10/2= 19/20
c) 1,05 * 2/3 - 0,46 =21/20x2/3-46/100= 7/10-23/50= 35/50-23/50= 12/50= 6/25
d) (72 - 2 * 9 ) : 1/2 = (72-18):1/2= 54:1/2= 54x2= 108
e) (2 - 7) * (6 : 1 1/5 ) = -5x(6*5/6)= -5x5= -25
f) (3/5) ²: (2/5) ² - ( 1,5 ) ² = 9/25:4/25-(3/2)²= 9/25*25/4-9/4= 9/4-9/4=0
g) ( -4 ) ² - ( -3 ) ² = 16-9= 7
