Final answer:
To find the answer, convert 7 halves of a cupcake to quarters and then add the result to 6 quarters. Finally, divide the total quarters by 4 to get the answer in cupcakes. The correct answer is option b) 19/4 cupcakes.
Step-by-step explanation:
To find the answer, we need to add 7 halves of a cupcake and 6 quarters together. First, let's convert the halves to quarters. Since there are 2 quarters in a half, 7 halves would be equal to 7 * 2 = 14 quarters. Now, we can add the 14 quarters to the original 6 quarters giving us a total of 20 quarters. To convert this back to cupcakes, we divide 20 quarters by 4 (since there are 4 quarters in a cupcake) and we get 20 / 4 = 5 cupcakes. Therefore, the answer is option b) 19/4 cupcakes.
