Explanation:

We can reword this problem as:

What is 1/7 of 6/7 cups?

In this context the word "of" means "the product of" or "times" or "multiplied by".

We can write the question in algebraic terms as the expression:

#1/7 xx 6/7#

To multiply fractions you multiply the numerators over the denominators multiplied:

#1/7 xx 6/7 = (1 xx 6)/(7 xx 7) => 6/49#

You would need #6/49# of a cup of granola to make #1/7# of the recipe.
