Berapakah hasil dari: (1) a. (-3/4+1/3)+5/6 b. (2/7+1/2)+(-3/4) (2) a. (-4/5)+3/10+3/2 b. (-3/8)+(-4/6)+(-3/4) TOLONG DIJAWAB YA:) BANTUIN SAYA BUAT PR, BESOK

1) a. (-3/4+1/3)+5/6
=(-9/12+4/12)+5/6
=-5/12+5/6
=-5/12+10/12
=5/12
b. (2/7+1/2)+(-3/4)
=8/28+14/28+ (-3/4)
=22/28-21/28
=1/28
(2) a. (-4/5)+3/10+3/2
=(-4/5)+ 3/10+15/10
=-8/10+18/10
=10/10
=1
b. (-3/8)+(-4/6)+(-3/4)
=-9/24-16/24-18/24
=-43/24
