Questions & Step-by-Step Solutions

A diet consists of 60% carbohydrates, 25% proteins, and 15% fats. If the total caloric intake is 2000 calories, how many calories come from fats? (2020)
  • Step 1: Understand that the diet is made up of different percentages: 60% carbohydrates, 25% proteins, and 15% fats.
  • Step 2: Know that the total caloric intake is 2000 calories.
  • Step 3: To find out how many calories come from fats, we need to calculate 15% of 2000 calories.
  • Step 4: Convert the percentage to a decimal. 15% as a decimal is 0.15.
  • Step 5: Multiply the total calories (2000) by the decimal (0.15): 0.15 * 2000.
  • Step 6: Calculate the result: 0.15 * 2000 = 300 calories.
  • Step 7: Conclude that there are 300 calories from fats in the diet.
