1 31/35 = 1 31/35

To divide (2-8/9) by 1 19/45, we need to first convert the mixed numbers to improper fractions.

2-8/9 = 18/9 - 8/9 = 10/9
1 19/45 = 45/45 + 19/45 = 64/45

So, the expression becomes 10/9 ÷ 64/45.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

10/9 ÷ 64/45 = 10/9 45/64
= (1045) / (9*64)
= 450 / 576
= 75 / 96
= 25 / 32

Therefore, the simplified result is 25/32.
