a) - 3 1/3 : 2 1/2 + ( - 4,2) * 3,5 = -10/3*2/5+ (-14,7)= -4/3+ (-14,7)= -1,33+(-14,7)= -16,03
b) 3,5+2,8:1 1/3=3,5+2 i 4/5: 1 i 1/3= 3,5+ 14/5*3/4= 3,5+21/10= 3,5+2,1=5,6
c) - 1,5 * ( 6 1/4 - 1 7/12) = -1,5* (25/4-19/12)= -1,5* (75/12-19/12)= -1,5* 56/12= -1 i 1/2*56/12= -3/2* 56/12= -28/4= -7
d) 8,2 - (4 1/2 - 0,5 ) = 8,2-(4,5-0,5)=8,2-4=4,2
