Answer 2

Answer:

-51/60

Step-by-step explanation:

let the other number be 'x'

by given information,

$7/12 + x = -4/15\\\\ =>x = -4/15 - 7/12\\\\ = [(-4)(4) + (-7)(5)]/60\\\\ = (-16 - 35)/60\\\\ = -51/60$

 

VERIFICATION

R.H.S = -4/15

L.H.S = $7/12 + x$

         = $7/12 + (-51/60)$

         = $35/60 - 51/60$

         = $(35-51)/60$

         = $-16/60$

         = $-4/15$  =  R.H.S

∵ L.H.S = R.H.S

∴ x = -51/60
