Answer 1

b.(4/9 + 2/3) * 27/16=

=(4/9+6/9)*27/16=

=10/9*27/16=

=270/144=135/72=15/8=1 7/8

c.(18i1/2 - 16i1/4) * 1i3/5=

=(37/2-65/4)*8/5=

=(74/4-65/4)*8/5=

=9/4*8/5=72/20=36/10=18/5=3 3/5

d.9/5 : (6i1/2 - 5i3/5) do potegi 2=

=9/5:(13/2-28/5)²=

=9/5:(65/10-56/10)²=

=9/5:(9/10)²=

=9/5:81/100=

=9/5*100/81=

=900/405=

=180/81=

=20/9=

=2 2/9

e.(2i1/3*(3i1/4 + 2i1/4) - 4i1/4) : 1i2/5=

=(7/3*(13/4+9/4)-17/4):7/5=

=(7/3*22/4-17/4):7/5=

=(154/12-17/4):7/5=

=(154/12-51/12):7/5=

=103/12*5/7=

=515/84=

=6 11/84

f.(16/3 - 2/9)* 39/16=

=(48/9-2/9)*39/16=

=46/9*39/16=

=1794/144=

=12 66/144=

=12 33/72

g.(7/6 + 2i1/8) : |2i2/3 - 3i1/2|=

=(7/6+17/8):|8/3-7/2|=

=(56/48+102/48):|16/6-21/6|=

=158/48:|-5/6|=

=158/48:5/6=

=158/48*6/5=

=948/240=

=237/60=

=79/20=

=3 19/20

h.(1i1/4 + 2i1/8 : (7i1/2 - 6i3/4)=

=(5/4+17/8:(15/2-27/4))=

= (5/4+17/8:(30/4-27/4))=

=(5/4+17/8:3/4)=

=(5/4+17/8*4/3)=

=5/4+ 68/24=

=30/24+68/24=

= 98/24=

= 49/12=

= 4 1/12
