What is 9/11 +2/3 and show the work

To add fractions you must have a common denominator (the bottom number)
9/11 + 2/3 , 11 and 3 are the denominators so the least common multiple is 33. you multiple 9/11 by 3
9/11 • 3
9•3/9•11
27/33
2/3 • 11
2•11/3•11
22/33
now you have the two fractions 27/33 and 22/33
you can easily add them, but you do not change the denominator
27/33 + 22/33
27+33= 60
33
answer is 60/33, but you should simplify to 20/11 or in mixed number form it’s 1 9/11
