Explanation:

Problem 1a

Step1: Identify the relationship

We know that Clare reads 24 pages in 60 minutes, and we want to find the time per page. So we divide the total time by the number of pages.
$$\text{Time per page} = \frac{\text{Total time}}{\text{Number of pages}} = \frac{60}{24}$$

Step2: Simplify the fraction

Simplify $\frac{60}{24}$ by dividing numerator and denominator by their greatest common divisor, which is 12.
$$\frac{60\div12}{24\div12}=\frac{5}{2} = 2.5$$

Step1: Identify the relationship

We want to find the number of pages per minute, so we divide the number of pages by the total time.
$$\text{Pages per minute} = \frac{\text{Number of pages}}{\text{Total time}}=\frac{24}{60}$$

Step2: Simplify the fraction

Simplify $\frac{24}{60}$ by dividing numerator and denominator by their greatest common divisor, which is 12.
$$\frac{24\div12}{60\div12}=\frac{2}{5}=0.4$$

Step1: Identify the relationship

Kiran uses 6 cups of flour for 4 pizzas, so we divide the total flour by the number of pizzas.
$$\text{Flour per pizza}=\frac{\text{Total flour}}{\text{Number of pizzas}}=\frac{6}{4}$$

Step2: Simplify the fraction

Simplify $\frac{6}{4}$ by dividing numerator and denominator by their greatest common divisor, which is 2.
$$\frac{6\div2}{4\div2}=\frac{3}{2} = 1.5$$

Answer:

2.5 minutes
