Explain Multiplying/Dividing Negative Fractions?

There are 3 steps to multiplying or dividing fractions.
1. If any negative signs are present, place them next to the numerator.
2. Multiply/Divide as you would for positive fractions, but follow the sign rules for multiplication/division of integers.
Example 1:
Multiply -2/3 x-5/7
-2/3x(-5)/7 = -2x(-5)/3x7 = 10/21
Example 2:
Divide (-1)/3 /(2/5)
(-1/3)/ 2/5 = (-1)/3 x5/2 = (-1) x5/3x2 = -5/6
