1/3 divided by 7/9?

The problem is written as ⅓ : 7/9

First, we need to find the reciprocal of 7/9, which is 9/7

Then, multiplying the fractions: ⅓*9/7

= (1*9)/(3*7)

= 3/63

Finally, we simplify the fractions by dividing both the 3 and 63 by the greatest common factor, which is 3 in this case: (3:3)/(63/3) = 1/21.
