Convert to improper fractions:
1 2/3 = 5 / 3 .............(1)
2 5/9 = 23 / 9 .
Turn 2nd fraction upside down:
9 / 23 ...........(2)
Multiply (1) by (2):
(9 x 5) / (3 x 23)
= 45 / 69
Divide numerator and denominator by 3:
15 / 23.

1 2/3 is a mixed number... And no one likes those, so let's transfer them into an improper fraction:
3*1= 3 + 2 = 5
So the improper fraction is:
5/3
And for 2 5/9
9*2 = 18 + 5 = 23
23/9
Now, we have 5/3 and 23/9:
(5/3) / (23/9)
To divide fractions, you flip the second fraction and multiply it by the first one.
(5/3)*(9/23)
To multiply, you just multiply the top numbers and the bottom numbers separately and combine them to make a final fraction:
5*9 / 3*23
= 45/69
This can be simplified by dividing both parts by 3:
15/23
And that is the final answer. Notice that is indeed smaller than the first fraction 1 2/3, so it is right.

Convert the mixed numerals to fractions:
(5/3) / (23/9)
Then divide the fractions the same way you divide two fractions: flip over the second one and multiply:
(5/3) * (9/23) =
(5*9) / (23*3) =
(5*3) / (23) =
15/23
