Question

(-3/4)(-7/15)(-8/21)(-5/9)

Answer 1

- 3/4 x - 7/15 = 21/60 = 7/20 (multiply first two)
- 8/21 x - 5/9 = 40/189 (multiply last two)
now multiply the answers you got ...
7/20 x 40/189 = 14/189 = 2/27

or...
-3/4x - 7/15 = 7/20 (multiply first two)
7/20 x - 8/21 = -14/105 (multiply answer by 3rd number)
-14/105 x - 5/9 = 14/189 = 2/27 (multiply answer by 4th number)

either way, you will get the same answer... 2/27
