Explanation:

Since the question stated,"what is the total"? That means we have to add both fractions.

We need to have common denominators.

The Least Common Multiple of 7 and 9 is 63.

Now we can add:

8 36/63 + 7 14/63 = 15 50 / 63.

We can't simplify this fraction.

Therefore, the recipe calls for 15 50/63 cups of flour.

Best of Luck to you.
