The difference between $\frac{3}{5}$ and $\frac{3}{8}$ is ___.

Given: $\frac{3}{5} \ -\ \frac{3}{8}$

To find: $\frac{3}{5} \ -\ \frac{3}{8}$

Solution:

$\frac{3}{5} \ -\ \frac{3}{8}$

Taking LCM of 5 and 8:

$=\ \frac{3( 8) \ -\ 3( 5)}{40}$

$=\ \frac{24\ -\ 15}{40}$

$=\ \frac{9}{40}$

So, the answer is $\frac{9}{40}$.
