Answer 2

It looks like you've provided two mathematical expressions. Let's break them down:

1. (12,33 + 7,3) ÷ 6,5

First, we need to add the numbers inside the parentheses:

12,33 + 7,3 = 19,63

Now, we can divide this sum by 6,5:

19,63 ÷ 6,5 ≈ 3

So, the result of the first expression is approximately 3.

2. (9 - 2,43) ÷ 4 1/4

First, subtract 2,43 from 9:

9 - 2,43 = 6,57

Now, divide this result by 4 1/4. To do this, you can convert 4 1/4 into an improper fraction, which is 17/4:

6,57 ÷ (17/4)

To divide by a fraction, you can multiply by its reciprocal (flip it):

6,57 × (4/17) ≈ 1,545

So, the result of the second expression is approximately 1,545.
