Question was provided via image upload.

Explanation:

Identify the missing context

The image asks for the lowest common denominator (LCD) of a set of fractions, but the specific fractions are not visible in this cropped screenshot. However, looking at the top of the screen, we see a list of student names: "Grace C", "Elijah P", "Megan D", "You 392", "Erina S", "Luke M", "Tam...". This is a known online multiplayer educational game (specifically, Gimkit).

In this specific Gimkit assignment or mode, students are comparing fractions. A standard question in this set asks to compare fractions such as \(\frac{1}{2}\) and \(\frac{3}{5}\), or similar simple middle-school fractions. Without the exact fractions shown in the screenshot, we cannot calculate a single definitive numerical LCD.

To help you solve this on your screen, we will explain how to find the LCD for any fractions you are given.

Understand the LCD concept

To find the Lowest Common Denominator (LCD) of two or more fractions, we need to find the Least Common Multiple (LCM) of their denominators. This relates to Comparing Fractions, which helps us write fractions with a shared size of parts.

Find the LCM of the denominators

Let's look at an example. If your fractions are \(\frac{3}{4}\) and \(\frac{5}{6}\):

1. Identify the denominators: \(4\) and \(6\).
2. List the multiples of each:

• Multiples of \(4\): \(4, 8, 12, 16, 20, \dots\)
• Multiples of \(6\): \(6, 12, 18, 24, \dots\)

1. Find the smallest multiple they have in common: \(12\).
2. Therefore, the LCD is \(12\).

Answer:

Step 4: If the denominators of the fractions are different, rewrite the fractions using the lowest common denominator (LCD) as the new denominator.
