let us see them one by one.

14/35 and 21/35

14/35= 2/5 (in simple terms)

21/35= 3/5 (in simple terms)

So this pair is not equivalent

-12/26 and 18/3

-12/26= -6/13 (in simple terms)

18/39 = 6/13 (in simple terms)

So this pair is not equivalent

-3/7 and -21/56

-3/7= -3/7 (in simple terms)

-21/56= -3/8 (in simple terms)

So this pair is not equivalent

-7/28 and -5/20

-7/28= -1/4 (in simple terms)

-5/20= -1/4 (in simple terms)

SO THIS PAIR OF RATIONAL NUMBERS

IS EQUIVALENT
