Final answer:
Kimberly used 6 cups of flour to make the chicken pizzas by first calculating 3.5 cups for the tortillas and then multiplying by 1.714 to represent 1(5/7) times more for the pizzas.
Step-by-step explanation:
To solve how many cups of flour Kimberly used for the chicken pizzas, first, we need to multiply the amount of flour used for tortillas by the given factor for the pizza. Kimberly used 3(1/2) cups of flour for tortillas, which is 3.5 cups. For the pizzas, she used 1(5/7) times as much flour as the tortillas, which simplifies to 1.714... times as much flour.
To find the total cups of flour for the pizza, we calculate:
3.5 cups * 1.714... = 6 cups (rounded to the nearest whole number)
Therefore, Kimberly used 6 cups of flour to make the chicken pizzas.
