A= 2/3 - 3/4 B= 4/5-2/7
= 8-9/12 =28-10/35
= -1/12 =18/35
= -0,083 = 0,514
C= -8/9- 5/4 D= 4/5-2
= -32+45/35 =4-10/5
= -77/36 =-6/5
= -2,138 =-1,2
E= -2/3+6/4 F= -2/3+-5/9
=-2/3+3/2 =-6-5/9
=-4+9/6 =-11/9
=5/6 = -1,2
=0,83
G= 2/7+-4/3 H= 5- -10/3
= 6-28/21 = 5+10/3
=-22/21 = 15+10/3
=-1,046 = 25/3
= 8,3
