Answer 1

a) ((3,2+7/8):2,5-0,62)*( -100/3)=

= ((32/10+7/8):2,5-0,62)*(-100/3)=

=(128/40+35/40):25/10-62/100)*(-100/3)=

=(163/40*10/25-62/100)*(-100/3)=

=(163/100-62/100)*(-100/3)=

=101/100*(-100/3)=

=-101/3=-33 i 2/3

 

b)4*(0,6-3/5:(-3))=

=4*(6/10-6/10*(-1/3)=

=4*(6/10+2/10)=

=4*8/10=

=32/10=3,2

 

c)((2 i 1/3 - 1 i 3/4)+5/12):(-0,02-0,08)=

=((7/3-7/4)+5/12):(-0,1)=

=((28/12-21/12)+5/12)*(-10)=

=(7/12+5/12)*(-10)=

=1*(-10)=-10

 

d) (-1/9+1 i 1/6):(1/6- 1i 1/3)=

=(-1/9+7/6):(1/6-4/3)=

=(-6/54+63/54):(1/6-8/6)=

=57/54:(-7/6)=

=57/54*(-6/7)=

=-342/378=-19/21

 

e)1,44:2 i 2/5-(0,75-1 1/3)* (-4/5)=

=144/100:12/5-(3/4-4/3)*(-4/5)=

=144/100*5/12-(9/12-16/12)*(-4/5)=

=12/20-(-7/12)*(-4/5)=

=12/20+7/12*(-4/5)=

=12/20-7/15=

=36/60-28/60=-8/60=-2/15

 

Wszystko się zgadza.

Pozdrawiam i licze na naj ;)
