Answer 1

(-1/4*-2/10):5/100- (81/100)-361/100= (1/20)*100/5-(81/100)-361/100=

= 5/5-81/100-361/100=1-442/100= 100/100-442/100= -342/100= -3 42/100= -3 21/50

 

-36/100*5/4)-3/10= -9/20-6/20=-9/20

 

(1/6+5/10)^2-(-1/3)^2*(-2)= (5/30+15/30)^2-(1/9)*(-2)=

= (20/30)^2+2/9=

=(2/3)^2+2/9= 4/9+2/9=6/9=2/3

Answer 2

[(-1/4)*(-0,2)]:0,05-(-9/10)^2 -19/10^2= [(-1/4)*(-1/5)]:0,05 - (81/100) -361/100)= 

 = 1/20 : 5/100 -81/100 -361/100= 1/20*100/5-81/100-361/100= 100/100 -442/100=

 = 1 - 4 i 42/100 = - 3 i 42/100= -3 i 21/50

 

(-0,36 : 4/5 ) - 0,3 = ( -0,36 : 0,8) - 0,3 = -0,45 - 0,3 = - 0,75

 

( 1/6 + 0,5) ^2 -(-1/3)^2 * (-2) = (1/6 +1/2)^2 -( 1/9) *(-2)= (1/6 + 3/6)^2 + 2/9 =

 = (4/6)^2 + 2/9 = 16/36 + 8/36 = 24/36 = 2/3
