Set determine the LCD of the above by inspection 1/9 5/18 three 6 1/90

To find the **Least Common Denominator (LCD)** of the given fractions:

### List of fractions:
\[
\frac{1}{9}, \frac{5}{18}, 3, \frac{1}{90}
\]

### Step 1: Express all numbers as fractions
First, convert the whole number \(3\) into a fraction:
\[
3 = \frac{3}{1}
\]

Now the list of fractions is:
\[
\frac{1}{9}, \frac{5}{18}, \frac{3}{1}, \frac{1}{90}
\]

### Step 2: Find the denominators
- Denominator of \(\frac{1}{9}\) is **9**
- Denominator of \(\frac{5}{18}\) is **18**
- Denominator of \(\frac{3}{1}\) is **1**
- Denominator of \(\frac{1}{90}\) is **90**

### Step 3: Find the Least Common Denominator (LCD)
The LCD is the **least common multiple (LCM)** of the denominators:
- Denominators: 9, 18, 1, 90

Now, find the LCM

Learn how to find the Least Common Denominator (LCD) of the fractions 1/9, 5/18, 3, and 1/90 with a step-by-step solution. This problem focuses on converting whole numbers into fractions and finding the Least Common Multiple (LCM) of the denominators. Ideal for students in Grades 5-7.
