Question

do 4/-9 and -16/36 represent the same rational number​

Answer 1

Answer:

both are same.

Step-by-step explanation:

we need to prove,

(4/-9) = (-16/36).

(4/-9)=-(4/9) .........(1)

-16/36=-(16/36) ..........(2)

16/36=(4*4/9*4)

=4/9 ...........(3)

from (3),

-(16/36)=-(4/9)

from (1) and (2),

(4/-9) = (-16/36).
