We can write a pair of fractions as fractions with common denominators by finding multiples of the denominators and using a common multiple as their common denominator. We will create a fraction pair that have the same denominators. A common denominator is a common multiple of the denominators of two or more fractions. We need common denominators to add, subtract, compare, or put fractions in order by their size. Fractions with different denominators represent wholes that are cut into a different amount of parts. Fractions with common denominators represent wholes that are cut into the same amount of parts. We can use paper folding to find a common denominator for a pair of fractions. By making common denominators for fractions, we can find out if they are equivalent fractions.
