Answer 2

Answer:

Step-by-step explanation:

product = 2/5

one number = -8/5

other number = unknown

so to find the other number we need to divide. Lets see --:

2              -8

----    ÷    -------  

5               5

now we will do the reciprocal of -8/5 (we need to multiply)

so,

2              5

----  ×      -------

5              -8

now cut 2 and -8 and your answer is -4

then cut 5 and 5 and your answer is 1

so your final answer is -4

-4 is the other number /  the unknown number
