What are the steps i need to learn to answer this question and what is this specific problem named.

Answer 1

To change a mixed number to an improper fraction multiply the denominator by the whole number, and then add the numerator.
(-2 1/2) is 2x2+1 —> 5/2

(-1 3/5) is 5x1 +3 —> 8/5

(-5/2)(-8/5) = 40/10 simplify 4/1 which equals to 4
IT’s positive because negative times negative gives you positive
(-)(-)= +
(+)(+)= +
(-)(+) = -
