given,

the fractions are 6/11, 7/9, 4/7, 2/3, 5/7

The LCM of 11,9,7,3=693

6/11 = 6/11(63/63) = 378/693

7/9 = 7/9(77/77) = 539/693

Answer 2

We'll be able to identify which among them is the biggest fraction by making them similar fractions.

But how?

*Identify their LCD or LCM of the denominators.
The LCM of the numberes 11, 9, 7, and 3 is 693

*LCM divided by denominator, then quotient times numerator; the product will be the new numerator.
693/11 = 63
63 * 6 = 378
6/11 = 378/693

693/9 = 77
77*7 = 539
7/9 = 539/693

693/7 = 99
99*4 = 396
4/7 = 396/693

693/3 = 231
231 * 2 = 462
2/3 = 462/693

693/7 = 99
99 * 5 = 495
5/7 = 495/693

Now, we have:
378/693, 539/693, 396/693, 426/693, 495/693

Which among them is the biggest? Just look at the numerator. And yep, the biggest is 539/693 which is equal to 7/9
