-3/2 - (-9/4)
= -3/2 + (9/-4 )
= -3/2 + -9/4
LCM of 2 and 4 = 4
= -3/2*2 = -6/4
-9/4*1 = -9/4
= -6-9/4
= -15/4
= -3/2 + (9/-4 )
= -3/2 + -9/4
LCM of 2 and 4 = 4
= -3/2*2 = -6/4
-9/4*1 = -9/4
= -6-9/4
= -15/4

Answer:
We know that we have to open brackets before we answer
Step-by-step explanation:
-3/2 - (-9/4)
= for answer we know it's l.c.m.
= l.c.m. is 4
= -3--9/4
have the answer we devide 4 by 2 = 2 ,and multiply 2 to 3 =6
and 4 ÷ 4 =1 and 1 multiply by 9 =9
we know that is - ,- =+
and +,- = -
= so, 6-9/4 = -3/4
