2.
a) x=3/8 y=3/8 x=y
b) x=5/9 y=5/9 x=y

3.
a) 5/12-7/18=90/216-84/216=6/216=1/36
b)5/12-7/18=15/36-14/36=1/36

a=1-0,125*1/2 / 7/8-8/7 = 1-1/16 / 49/56-64/56 = 15/16 / -15/56 = -7/2
b=2 3/5 * 4 6/11 * 3 5/13 * (-1/4) = 13/5*47/11*44/13**1/4=-26884/2860=-47/5=-9,4
c=24/11*1,5*2,75*(-1 1/3 ) = 24/11*15/10*275/100*(-4/3)=24/11*3/2*11/4*(-4/3)=-132/11=-12
