Answer: 26/3 or 8 2/3
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
