To find the number of calories per serving based on the recipe, you need to first calculate the total calories from the yogurt used and then divide that by the number of servings.
-
Calculate the total calories from the yogurt:
- You need 1/3 of a container of yogurt, and each container has 150 calories.
- Total calories from yogurt = \( \frac{1}{3} \times 150 \).
-
Divide the total calories by the number of servings:
- The recipe makes 4 servings, so you would then divide the total calories by 4.
Putting it all together, the correct calculation is:
\[ \frac{1}{3} \times 150 \div 4 \]
So, the correct set of calculations that would give the correct number of calories per serving is:
1/3 × 150 ÷ 4.
