Answer:


(36)/(54) and
(6)/(9)

Explanation:

We are given that some fractions

We have to find the pair of fractions which are proportional

We know that if fraction


(a)/(b) ,(c)/(d) are proportional

Then , product of a and d is equal to product of b and c.

In
(14)/(35)\; and \;(21)/(42)

Product of 14 and 42


14* 42=588

Product of 35 and 21


35* 21=735

Hence,
(14)/(35) and
(21)/(42) are not proportional.

2.
(6)/(7)\;and\;(16)/(21)

Product of 6 and 21


6*21=126

Product of 7 and 16


7* 16=112

Hence, they are not proportional.

3.
(36)/(54) and
(6)/(9)

Product of 36 and 9


36* 9=324

Product of 54 and 6


54* 6=324

Hence, the pair of fractions are proportional.

4.
(21)/(36) and
(14)/(25)

Product of 21 and 25


21* 25=525

Product of 36 and 14


36* 14=504

Hence, pair of fractions are proportional.
