Step 2: Simplify:




Step 3: 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 5: 5, 10, 15…

Multiples of 3: 3, 6, 9, 12, 15…

Therefore, the LCD is 15.

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 3: 3

Prime factors of 5: 5

Therefore, the LCD is 3 x 5 = 15.

Step 4: Make the denominators the same as the LCD.




Step 5: Simplify. The denominators are now the same.




Step 6: Join the denominators.




Step 7: Simplify.




Step 6: Convert to a mixed number.

Step 2: Since 4 is less than 9, borrow 1 from the next column. 3 becomes 2 and 4 becomes 14.




Step 3: Calculate 14 – 9 = 5




Step 4: Calculate 2 – 2 = 0
