Difference between like and unlike fractions

Like Fractions:

  • Like fractions have the same denominators.
  • When the denominators are the same, the fractions have a similar structure and are easier to compare and perform operations on.
  • For example, 1/4 and 3/4 are like fractions because they have the same denominator of 4.

Unlike Fractions:

  • Unlike fractions have different denominators.
  • When the denominators are different, the fractions have a different structure and cannot be compared or operated on directly.
  • To compare or perform operations on unlike fractions, they need to be converted into like fractions by finding a common denominator.
  • For example, 1/4 and 2/5 are unlike fractions because they have different denominators of 4 and 5, respectively. To compare or add these fractions, we need to find a common denominator, such as 20, and convert them into like fractions (5/20 and 8/20).
