What is the process to simplify a fraction?

• To multiply both the numerator and the denominator by their least common multiple (LCM).

• To divide both the numerator and the denominator by their greatest common divisor (GCD).

• To add the numerator and the denominator together.

• To subtract the numerator from the denominator.

What does it mean for two fractions to be equivalent?

• Two fractions are equivalent if they represent the same part of a whole, even if they have different numerators and denominators.

• Two fractions are equivalent if they have the same numerator and denominator.

• Two fractions are equivalent if their decimal representations are the same.

What is an improper fraction?

• A fraction where the numerator is less than the denominator, such as @@\frac{1}{2}@@.

• A fraction where the numerator is equal to the denominator, such as @@\frac{3}{3}@@.

How do you find an equivalent fraction?

• By adding the same number to the numerator and denominator.

• By multiplying or dividing both the numerator and the denominator by the same non-zero number.

• By subtracting the same number from the numerator and denominator.

How do you add fractions with the same denominator?

• Add the numerators and keep the denominator the same. For example, @@\frac{1}{4} + \frac{2}{4} = \frac{3}{4}@@

• Multiply the numerators and add the denominators.

• Add the denominators and keep the numerator the same.
