Q
Q: If a person needs 2500 calories a day and wants to get 20% of their calories from fats, how many grams of fat should they consume (1 gram of fat = 9 calories)?
Solution: 20% of 2500 calories = 0.20 * 2500 = 500 calories from fats. 500 calories / 9 calories per gram = 55.56 grams, rounded to 56 grams.
Steps: 7
Step 1: Determine the total daily calorie intake, which is 2500 calories.
Step 2: Calculate 20% of the total calories to find out how many calories should come from fats. This is done by multiplying 2500 by 0.20.
Step 3: Perform the multiplication: 0.20 * 2500 = 500 calories from fats.
Step 4: Know that 1 gram of fat equals 9 calories.
Step 5: To find out how many grams of fat are needed, divide the calories from fats (500) by the calories per gram of fat (9).
Step 6: Perform the division: 500 calories / 9 calories per gram = approximately 55.56 grams of fat.
Step 7: Round the result to the nearest whole number, which is 56 grams of fat.
