Final answer:
Andy will need to use the 1/12 measuring cup a total of 17 times to measure out 3/4 cup of chocolate chips and 4/6 cup of flour for his cookie recipe.
Step-by-step explanation:
The task is to determine how many times Andy needs to use the 1/12 measuring cup to measure out all of his dry ingredients for the cookies. He needs 3/4 cup of chocolate chips and 4/6 cup (which simplifies to 2/3 cup) of flour. To find out how many 1/12 cups are in 3/4 cups, we calculate (3/4) / (1/12) = 3/4 × 12/1 = 9. Similarly, for 4/6 cups, we simplify the fraction to 2/3 and calculate (2/3) / (1/12) = 2/3 × 12/1 = 8. So, for the chocolate chips, Andy would use the 1/12 measuring cup 9 times, and for the flour, he would use it 8 times. Adding these together, 9 + 8 = 17. Hence, Andy will use the 1/12 measuring cup a total of 17 times to measure out both the chocolate chips and the flour.
