Step 1: Find the Least Common Denominator (LCD). There are two ways we can do this:
Method 1: Find the first common multiple List out all multiples of each denominator and find the first common one.
Multiples of 9: 9, 18, 27…
Multiples of 6: 6, 12, 18…
Multiples of 18: 18, 36…
Therefore, the LCD is 18.
Method 2: Prime Factors. The LCD will be the product of the largest multiple of each prime that appears on at least one list.
Prime factors of 9: 3, 3Prime factors of 6: 2, 3
Prime factors of 18: 2, 3, 3
Therefore, the LCD is 3 x 3 × 2 = 18.
Step 2: Make the denominators the same as the LCD.
