Enter a fraction to see its simplest form and a list of equivalent fractions. Adjust the count to see more or fewer equivalents.
- Enter the numerator and denominator. Type the fraction you want to find equivalents for.
- Set the count (optional). Choose how many equivalent fractions to display, from 1 to 50. Default is 10.
- Read the results. The simplest form appears at the top, followed by a list of equivalent fractions. Each shows the multiplier used to generate it from the simplest form.
The calculator first reduces your fraction to lowest terms, then generates equivalents by multiplying both the numerator and denominator by 1, 2, 3, and so on.
About Equivalent Fractions
Equivalent fractions are fractions that represent the same value despite having different numerators and denominators. For example, 1/2, 2/4, 3/6, and 4/8 are all equivalent. They look different but represent the same proportion.
Understanding equivalent fractions is essential for adding and subtracting fractions (which requires a common denominator), comparing fractions, and simplifying expressions. Any fraction can generate infinitely many equivalents by multiplying both parts by the same integer.
Frequently Asked Questions
How do you find equivalent fractions?
Multiply (or divide) both the numerator and denominator by the same number. For example, 1/3 multiplied by 2/2 gives 2/6, by 3/3 gives 3/9, and so on. All are equivalent to 1/3.
How do you check if two fractions are equivalent?
Cross-multiply: if a/b and c/d are equivalent, then a x d = b x c. For example, 2/3 and 6/9: 2 x 9 = 18 and 3 x 6 = 18. They are equal, so the fractions are equivalent.
Why are equivalent fractions important?
You need them to add or subtract fractions with different denominators. By converting fractions to equivalents with a common denominator, the arithmetic becomes straightforward. They are also used to compare fractions and simplify algebraic expressions.
