Answer 1

1) 19,5 : 7 2/9 = 19 5/10 : 65/9 = 19 1/2 : 65/8 = 39/2 : 65/9 = 351/130 = 2,7
2) 24 4/5 - 2,7 = 124/5 - 27/10 = 248/10 - 27/10 = 221/10 = 22,1

Answer 2

It looks like you've provided a series of numbers and mathematical operations. Let's break it down step by step:

1. 224_ - This appears to be a number, 224.
2. 19,5 : 7 - This looks like a division operation, where 19.5 is divided by 7.
3. 5 - This is a standalone number, 5.
4. 9 - This is another standalone number, 9.

If we perform the calculations:

1. 224
2. 19.5 / 7 ≈ 2.7857 (rounded to 4 decimal places)
3. 5
4. 9

The series of calculations would be: 224 - 2.7857 + 5 + 9.

Performing the calculations: 224 - 2.7857 + 5 + 9 ≈ 235.2143

So, the result of the given expressions is approximately 235.2143.
