7 x -1/-7 x -5/8?



Answers:
7 x (-1/-7) x (-5/8)
= 7x (1/7) x (-5/8)
= 1 x (-5/8)
= -5/8

where 7 equals 7/1
7/1 x 1/7 becomes 1 because the nominator nad denominator is the same number -- 7 -- and thus can be striked out..
Okay, mathematical question:

1. convert 7 into fraction form 7/1

2. 7/1 x -1/-7 = -7/-7 or +1

3. convert +1 into fraction 1/1

4. 1/1 x -5/-8 = -5/-8

-50/-7 X -5/8
-400/35
-80/7
-11.3/7
