Question 105754
First let me introduce to you how to express one as a fraction.

{{{1=2/2=3/3=4/4=5/5=6/6=7/7=8/8=9/9=10/10=11/11=12/12=13/13=14/14}}}

And so on. The numerator should be equal to the denominator to express one as a fraction


Back to your problem,

13 2/5=13+2/5


{{{13+2/5=13(1) +(2/5)}}}
{{{13+2/5=13(5/5)+(2/5)}}}
{{{13+2/5=(13*5/5)+(2/5)}}}
{{{13+2/5=(165/5)+(2/5)}}}
{{{13+2/5=(165+2)/(5)}}}
{{{13+2/5=167/5}}}


This is the improper fraction for 13 2/5!
