Comparing Fractions. Let us compare fractions with unlike numerators. 3 5 a n d 4 5 . Since the denominators are the same, only numerators, i.e., 3 and 4 will be compared. We can say that 3 5 < 4 5 a s 3 < 4 . B. Add Fractions. Subtracting fractions with unlike denominators involves a four-step process: Identify the Least Common Denominator (LCD) Rewrite the fractions with the LCD. Subtract the numerators. Simplify the resulting fraction if possible. Children may find these steps challenging initially, but with enough practice, it becomes an easy task. When working with fractions, we keep the denominator in factored form because after it is converted to the common denominator, the addition / subtraction does not change the denominator. We only add/subtract numerators.
