Answer:
the answer is A
Explanation:
-1 × (- 8/7) × 7/8 ( multiplying an even number of negative terms makes the product positive)
1 × 8/7 × 7/8 ( any number that is multiplied by 1 stays the same)
8/7 × 7/8 ( reduce the numbers with the greatest common factor 8 )
and then we have 1/7 × 1/7 (reduce the numbers with the greatest common factor 7)
and we have 1 , good luck
