Answer 1

\[10(11/12)\]
the easiest way i know how is to change all numbers into improper fractions. (4/3), (25/6), (6/4), (15/12), (8/3). Find the greatest common factor, 12, and change the denominator in all the fraction to be the greatest common factor. (16/12), (50/12), (18/12), (15/12), (32/12). Add all those together and you get 131/12. divide 131 by 12 and put the whole number with the remainder.
