Final answer:
The ratio of the amount of flour to the amount of shortening is 18 cups.
Step-by-step explanation:
To write the ratio of the amount of flour to the amount of shortening, we can divide the amount of flour by the amount of shortening. In this case, it would be 6 cups divided by 1/3 cup. To divide fractions, we can multiply the first fraction by the reciprocal (or inverse) of the second fraction. So, the ratio would be 6 cups divided by 1/3 cup, which is the same as 6 cups multiplied by 3/1 cup. Simplifying this, we get 18/1 cup, which can be written as 18 cups.
