Answer:
-9/14
Step-by-step explanation:
This is my simplest-
Do the keep-change-flip method for this problem (and also any problem involving this)
KEEP -3/8
CHANGE the division sign to multiplication
FLIP the last fraction. 7/12 to 12/7
Now solve the problem by multiplying the fractions
-3/8 × 12/7 =
-3 × 12 = -36
8 × 7 = 56
-36 / 56 =
Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14
