$\frac{3}{5} + \frac{2}{8}$ $3/5+2/8$

by simplifying the second fraction,

$= \frac{3}{5} + \frac{1}{4}$ $=3/5+1/4$

by finding the common denominator $5 \cdot 4 = 20$ $5cdot4=20$ ,

(Multiply $\frac{3}{5}$ $3/5$ by $\frac{4}{4}$ $4/4$ and $\frac{1}{4}$ $1/4$ by $\frac{5}{5}$ $5/5$ )

$= \frac{3 \cdot 4}{5 \cdot 4} + \frac{1 \cdot 5}{4 \cdot 5} = \frac{12}{20} + \frac{5}{20}$ $={3cdot4}/{5cdot4}+{1cdot5}/{4cdot5}=12/20+5/20$

by combining the fractions,

$= \frac{12 + 5}{20} = \frac{17}{20}$ $={12+5}/20=17/20$

I hope that this was helpful.
