To solve this expression, we first need to simplify the calculation inside the parentheses.

2 2/3 * 2 5/8 can be converted to improper fractions:

2 2/3 = (32 + 2)/3 = 8/3
2 5/8 = (82 + 5)/8 = 21/8

Now, we multiply these fractions:

8/3 21/8 = (821)/(3*8) = 168/24 = 7

Now substitute this result back into the original expression:

4,5 • (3 4/9 - 7)

Next, simplify the subtraction inside the parentheses:

3 4/9 = (9*3 + 4)/9 = 31/9

Now, substitute this result back into the expression:

4,5 • (31/9 - 7)

Now, calculate the subtraction inside the parentheses:

31/9 - 7 = (31-63)/9 = -32/9

Finally, substitute this result back into the expression:

4,5 • (-32/9)

Now, multiply 4,5 by -32/9:

4,5 * (-32/9) = -14,4

Therefore, the final result is -14,4.
