Answer: 26/3 or 8 2/3

Step-by-step explanation:

In the addition or subtraction of fraction, first, you have to convert all of them into improper fraction if they are mixed; then, you need to find the LCD (Least Common Denominator).

Converting fraction:

5 3/4=23/4

2 11/12=35/12

Finding LCD:

4 and 12 is 12

Converting fraction into common denominator:

23/4=69/12

35/12=35/12

Solve:

 5 3/4 + 2 11/12

=69/12 + 35/12

=104/12

=26/3
