13.875

Explanation:

since a mixed fraction is given, first convert it to an improper fraction.
(conversion of a mixed fraction to an improper fraction: multiply the denominator by the whole number in the fraction and then add the numerator to the answer. In this question, 8*4+5=37)
That will give us:

#3*37/8#

next multiply 37 by 3 and divide the answer by 8.

#37*3#=111

#111/8#= 13.875
