Answer 2

To solve this expression, we'll first need to convert the mixed numbers into improper fractions:

32/5 = (5 x 6 + 2)/5 = 32/5 and 12/15 = 4/5

So we have:

23/45 ÷ (32/5 - 4/5)

To simplify the expression, we'll start by subtracting the fractions inside the parentheses:

32/5 - 4/5 = (32 - 4)/5 = 28/5

Now we can substitute this back into the original expression:

23/45 ÷ 28/5

To divide by a fraction, we can multiply by its reciprocal:

23/45 x 5/28 = (23 x 5)/(45 x 28) = 115/1260

The final answer is 115/1260, which can be simplified by dividing both the numerator and denominator by their greatest common factor of 5:

115/1260 = (23 x 5)/(252 x 5) = 23/252

Therefore, 23/45 ÷ (3 2/5 - 1 2/15) = 23/252.
