i hope u will find ur answer

Answer 2

Answer:

Option d

Step-by-step explanation:

5/7 < 7/9 < 9/11 < 11/13

Trick :

If the denominator - numerator difference is same in all the fractions, the one with small numerator will be smallest.

Eg: check --- 1/2, 2/3

1/2 =. 5........... 2/3 =.666...

1/2 has smallest numerator and is the smallest (of the two)

Or

Take option 'a'

5/7 ==. 71 (approx)

9/11 ===. 81 (approx)

11/13 ==. 84

7/9 ===.77...(approx)

Now one can easily check and write in ascending order, thereby identify the correct option [option d]

There are other methods too to arrive at the answer (like cross multiplication and comparing, lcm etc)
