1 ounce of cheddar cheese contains 9 grams of fat, and 6 grams of that fat are saturated fats. If you are trying to find the ratio of saturated fats to total fat in an ounce, all you have to do is substitute the integers (that we have already been given) into this ratio.
Therefore, the ratio of saturated fats to total fat in an ounce of cheddar cheese is 6:9.
