If a nutrition bar contains 40 grams of carbohydrates and 10 grams of sugar, what percentage of carbohydrates represent sugars?

  1. 20%

  2. 25%

  3. 30%

  4. 15%

The correct answer is: 25%

To determine what percentage of carbohydrates in the nutrition bar comes from sugars, you need to calculate the ratio of sugar to total carbohydrates and then convert that ratio into a percentage. In this case, the nutrition bar has 10 grams of sugar and 40 grams of total carbohydrates. To find the percentage of carbohydrates that are sugars, you use the formula: \[ \text{Percentage of sugars} = \left( \frac{\text{grams of sugar}}{\text{total grams of carbohydrates}} \right) \times 100 \] Substituting in the numbers: \[ \text{Percentage of sugars} = \left( \frac{10 \text{ grams}}{40 \text{ grams}} \right) \times 100 = \left( 0.25 \right) \times 100 = 25\% \] This calculation shows that 25% of the carbohydrates in the bar are from sugars, making that answer correct. The other options do not accurately represent this calculation. For instance, 20%, 30%, and 15% do not derive from dividing the amount of sugar by the total carbohydrates and thus do not reflect the correct portion that sugars contribute to the overall carbohydrate
