50. Are 0.025 and -40 reciprocals?

52. Describe how you would perform the following multiplication:

(-1/6)(1/5)(1/4)(-1/3)(-1/2)(-1)(2)(-3...

Answer 1

42 and 44. Division by 0 is illegal, but 0 divided by something is perfectly fine

46 to 52. Reciprocal means

reciporacle of x/y = y/x

46. -8/1 --> -1/8 (it doesn't matter where you put the negatives)

52. Assuming it goes up to -6. You would -6 by (-1/6) to get 1, 5 by (1/5) to get 1, etc. until all you have left is 1's and the -1, which comes out to -1.
