<em>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.</em>
-2/3 x -6/1
<em>Multiply across, numerator with numerator and denominator with denominator.</em><em>Also, when multiplying or dividing negative numbers, two negatives make a positive (i.e. -2 x -6 = +12)</em>
It's definitely a low data overlap. It's not medium because there's not a solid amount of matching data, and its not 'none' because there is matching data. so it’s C.
