23/24

Explanation:

Answer 2

23/24

Explanation:

I found a common denominator of 24, and then multiplied the numbers so that they would equal the common denominator. I then added all of the numbers up, to get an answer of 37/24. Finally, I subtracted 2 12/24 (which is equal to 2 1/2) to get an answer of 23/24. Because that cannot be simplified, that would be your final answer. Hope this helps :)
