Answer 2

To solve the expression, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions. 2 3/4 becomes (24 + 3)/4 = 11/4. 3 1/3 becomes (33 + 1)/3 = 10/3. 2 1/6 becomes (26 + 1)/6 = 13/6. 1 1/2 becomes (12 + 1)/2 = 3/2.

Now let's solve the expression:

2 3/4 : 1 = 11/4 : 1 = 11/4.

1,1 + 3 1/3 = 1.1 + 10/3 = 1.1 + 10/3 = 3.4/3 + 10/3 = (3.4 + 10)/3 = 13.4/3.

2,5 - 0,4 = 2.5 - 0.4 = 2.1.

3 1/3 : 5/7 = 10/3 : 5/7 = 10/3 * 7/5 = (10 * 7)/(3 * 5) = 70/15.

(2 1/6 + 4.5) = (13/6 + 4.5) = (13/6 + 27/6) = 40/6 = 20/3.

(2 1/6 + 4.5) * 0.375 = (20/3) * 0.375 = 20/3 * 3/8 = (20 * 3)/(3 * 8) = 60/24 = 5/2.

0.375 / 2.75 = 375/1000 / 275/1000 = 375/1000 * 1000/275 = 375/275 = 15/11.

Now let's put it all together:

11/4 - (13.4/3 - 2.1 * 70/15 - (20/3 + 4.5) * 5/2 - 15/11)

= 11/4 - (40.8/3 - 2.1 * 70/15 - (20/3 + 4.5) * 5/2 - 15/11)

= 11/4 - (40.8/3 - 2.1 * 70/15 - (20/3 + 4.5) * 5/2 - 15/11)

= 11/4 - (40.8/3 - 2.1 * 70/15 - (20/3 + 4.5) * 5/2 - 15/11)

= 11/4 - (40.8/3 - 2.1 * 70/15 - (20/3 + 4.5) * 5/2 - 15/11)

Calculating the expression within the parentheses:

= 11/4 - (40.8/3 - 9.333333333333334 - (6.666666666666667 + 4.5) * 5/2 - 15/11)

= 11/4 - (40.8/3 - 9.333333333333334 - 11.166666666666666 * 5/2 - 15/11)

= 11/4 - (40.8/3 - 9.333333333
