A recipe calls for 1/3 of a container of yogurt. Each container of yogurt has 150 calories. The recipe makes 4 servings. Which set of calculations would give the correct number of calories per serving?
1/3 x 150 divide 4
1/3 x 150 divide 1/4
1/3 x 150 x 4
1/3 divide 150 divide 4
To find the correct number of calories per serving, you would perform the calculation 1/3 x 150 divided by 4.
The correct set of calculations would be:
1/3 x 150 ÷ 4
This means you need to first multiply 1/3 by 150 and then divide the result by 4.
By using this calculation, you will find the correct number of calories per serving.
To find the correct number of calories per serving, you need to multiply the fraction of the container of yogurt used by the number of calories in a full container, and then divide by the number of servings.
The correct set of calculations is:
1/3 x 150 calories ÷ 4 servings
Explanation:
1. Multiply: 1/3 x 150 calories = 50 calories. This gives you the number of calories in the fraction of the container used.
2. Divide: 50 calories ÷ 4 servings = 12.5 calories. This gives you the number of calories per serving.
So, the correct calculation is:
1/3 x 150 ÷ 4 = 12.5 calories per serving.
The other options:
1. 1/3 x 150 ÷ 1/4 would give you an incorrect result because multiplying by 1/4 in the numerator cancels out multiplying by 4 in the denominator, resulting in the same value of 1/3 x 150.
2. 1/3 x 150 x 4 would give you an incorrect result because this calculates the total number of calories used in the recipe, instead of the number of calories per serving.
3. 1/3 ÷ 150 ÷ 4 would give you an incorrect result because dividing by 150 would result in an extremely small value, and then dividing by 4 would make it even smaller.
