Answer:
4
Explanation:
Since you can't divide a fraction by another fraction, you start by flipping the second fraction (-1/6 becomes -6/1) and changing the division sign to multiplication.
-2/3 x -6/1
Multiply across, numerator with numerator and denominator with denominator. Also, when multiplying or dividing negative numbers, two negatives make a positive (i.e. -2 x -6 = +12)
-2/3 x -6/1 = 12/3
12/3 = 4
