[tex]\boxed {\frac{1}{7} }[/tex] of Sarah's photo is photos is of her friends.
Further Explanation
Given:
- [tex]\frac{3}{7}[/tex] of the photos are of nature
- [tex]\frac{1}{4}[/tex] of the rest are her friends
Question:
What fraction of all of Sarah photos is of her friends?
Let's say that total of the photos 1, If [tex]\frac{3}{7}[/tex] of the photos are of nature, the fraction of the rest is :
[tex]\boxed {= 1-\frac{3}{7} = \frac{7}{7} - \frac{3}{7} = \frac{4}{7} }[/tex]
So the rest photo is [tex]\frac{4}{7}[/tex] 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:
[tex]\boxed {= \frac{1}{4} \times \frac{4}{7} }\\ \boxed {= \frac{4}{28} = \frac{1}{7} }[/tex]
So [tex]\boxed {\frac{1}{7} }[/tex] of the photos is of Sarah's friends.
