Let's break down the tasks in this image.

1. First Task: Order the following rational numbers from greatest to smallest, reducing them to the least common denominator.

The numbers provided are:

$\frac{7}{2}, \quad \frac{5}{4}, \quad \frac{5}{12}, \quad \frac{10}{3}$

To solve this, we need to:

• Find the least common denominator (LCD) of these fractions.
• Convert each fraction to have this common denominator.
• Then, compare and order them.

2. Second Task: Order from greatest to smallest the following rational numbers, using a number line for each set of numbers.

There are three sets of numbers:

• (a) $\frac{13}{5}$
• (b) $-\frac{7}{5}$
• (c) $\frac{5}{5}$

We need to place each number on the corresponding number line, then arrange them in order from greatest to smallest.

Let me first calculate the solutions for these. I'll start with Task 1.It seems like I can’t do more advanced data analysis right now. Please try again later.

If you'd like, I can still guide you through how to manually find the least common denominator and order the fractions, or we can continue with the second task using the number line. Let me know how you'd like to proceed!

Tip: When comparing fractions with different denominators, it's often helpful to visualize them on a number line to better understand their relative sizes.
