Following the nutritional label on the jar of peanut butter. you determine that 1 ounce of the peanut butter contains 115 calories and 9 grams of fat what percent of calories come from fat?

A.30
b.40
c.70
d.80

Involves conversion and math.

To determine the percent of calories that come from fat, we need to first find out how many calories are from fat in 1 ounce of peanut butter.

Given that 1 ounce of peanut butter contains 115 calories and 9 grams of fat, we know that 1 gram of fat contains 9 calories. Therefore, to find out how many calories are from fat, we multiply the grams of fat by the calories per gram of fat.

9 grams of fat * 9 calories per gram = 81 calories from fat

Now that we know there are 81 calories from fat, we can calculate the percentage by dividing it by the total calories (115) and multiplying by 100.

(81 calories / 115 total calories) * 100 = 70.43

So approximately 70% of the calories in 1 ounce of peanut butter come from fat.

Therefore, the correct answer is c. 70.
