To add fractions, you need to express all of the fractions with the same common denominator. In this case, the common deonominator is 12. So you need to express each of the given fractions as an equivalent fractions with a denominator of 12.
5a/6= 10a/12
a/4= 3a/12
2a/3= 8a/12
so 5a/6-a/4+2a/3 = 10a/12-3a/12+8a/12
You can now add the terms together
10a/12-3a/12+8a/12 = 15a/12
You can rduce to lowest terms by dividing both the numerator and the denominator by 3
The answer is 5a/4
