Mixed Numbers & Impr oper Fractions Fractions in Simplest Form To subtract fractions with the same denominator: + = = 3 6 2 6 5 6 = + 2 6 5 6 + 3 8 2 8 1 8 = 3 8 2 8 1 8 = Parts of a Whole Part of a Group A fraction is used to describe a part of a whole. A fraction can also describe part of a group or set. Equivalent fractions are fractions with different numerators and denominators but have the same value. To find an equivalent fraction, multiply or divide the numerator and denominator of a fraction by the same number. Equivalent Fractions To find the simplest form of a fraction, keep dividing until 1 is the only number that divides both the numerator and denominator.
