Let's say that total of the photos 1, If $\frac{3}{7}$ of the photos are of nature, the fraction of the rest is :

$\boxed {= 1-\frac{3}{7} = \frac{7}{7} - \frac{3}{7} = \frac{4}{7} }$

So the rest photo is $\frac{4}{7}$ which means the photo that are not nature photos.

Next step, we are going to calcultae the fraction of photos is of Sarah's friend:

$\boxed {= \frac{1}{4} \times \frac{4}{7} }\\ \boxed {= \frac{4}{28} = \frac{1}{7} }$
