You have to change the mixed fractions into improper fractions. To do this multiply the denominator by the whole number, then add the numerator.
So.. 5*3=15+3=18 => 18/5
3*1=3+2=5 => 5/3
Now you have to make common denominators in order to add them together. Find a common multiple. For 3 and 5, that is 15. Multiply both the numerator and denominator by the number necessary for the denominator to equal 15.
For 18/5, multiply both the numerator and denominator by 3 to equal 54/15.
For 5/3, this will then equal 25/15.
Now add the numerators.. 25+54=79 => 79/15
This can then be changed back into a mixed fraction! 15 4/15 :)
