Step-by-step explanation:
i)
3/2×(-1/6)+(-5/4)÷3/4-2/3
=3/2×(-1/6)-5/4÷3/4-2/3
=3/2×(-1/6)-5/4×4/3-2/3
= -1/4-5/3-2/3
= -1/4-(5-2/3)
= -1/4-3/3
= -1/4-1
= -1-4/4
= -5/4
ii)
-4/9÷5/3-11/6×7/2+3/4+(-9/2)
= -4/9÷5/3-11/6×7/2+3/4-9/2
= -4/9×3/5-11/6×7/2+3/4-9/2
= -4/15-77/12+3/4-9/2
= -16-385/60+3/4-9/2
= -401/60+3/4-9/2
= -401+45/60-9/2
= -356/60-9/2
= -356-270/60
= -626/60
= -313/30
