Q .Find the fraction which is lass then 3 / 9 and greater then 3 / 9.

Let x is the number which is less then 3 / 9 and greater then 3 / 9

so 3 / 9 < x < 8 / 7

Lets take the lcm - 63 and make the denominator 63

3 / 9 * 7 / 7 < x <8 / 7 * 9 / 9

= 21 /63 < x < 72 / 63

x = 51 / 63

51 / 63 is lass then 3 / 9 and greater then 8 / 7.
