Answer:

Step-by-step explanation:

let the two  numbers be a and b

given a*b= - 19/60

if one number is -7/12

let a= -7/12

then b=( - 19/60) / (-7/12)

          = 19/35

the other number is 19/35...

hope it helps......

Answer 2

Answer:

let one rational number is x

another rational number is 7/12

sum is -19/60

$x + \frac{7}{12} = - \frac{19}{60}$

$\frac{12x + 7}{12} = - \frac{19}{60}$

$\frac{12x + 7}{1} = - \frac{19}{5}$

60x+7=-19

60x=-19-7

60x=--26

x=-26/60

=-13/30
