Frequently asked questions
How do you add fractions with different denominators?
To add fractions with different denominators: (1) find the least common denominator (LCD), (2) convert each fraction to an equivalent fraction with the LCD, (3) add the numerators. For example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.
How do you simplify a fraction?
Divide both the numerator and denominator by their Greatest Common Factor (GCF). For example, 12/18: GCF of 12 and 18 is 6. 12/6 = 2, 18/6 = 3. Simplified fraction = 2/3.
