3/8    +  2/10   =

 

3/8  +  1/5     ......here's an easy way once we have reduced both fractions to lowest  terms

 

[  multiply  each demoninator by the other  fraction's numerator  and sum these products  ]  / [ multiply the denominators]   =

 

[ 8 * 1  +  5 * 3   ]   / [   8 * 5 ]  =

 

[8  + 15  ]  / 40  =  

 

23 / 40
