We have the sum:
[tex]3+\frac{3}{5}+1+\frac{1}{4}[/tex]We can simplify it by finding a common denominator.
The least common denominator is 20, that is 5*4, so we can write:
[tex]\begin{gathered} \frac{3\cdot20+3\cdot4+1\cdot20+1\cdot5}{20} \\ \frac{60+12+20+5}{20} \\ \frac{97}{20} \end{gathered}[/tex]Answer: the sum is 97/20
