What Is a Fraction Calculator?
A fraction calculator helps you quickly solve operations involving fractions — including addition, subtraction, multiplication, and division. It's great for students, teachers, and anyone dealing with math homework or practical fractions in daily life.
Fraction Formulas & Real-World Examples
Understanding how fractions work in real life helps reinforce math concepts. Here are the basic formulas we use when solving fractions:
Add or Subtract Fractions:
a/b ± c/d = (ad ± bc) / bd
Find a common denominator and apply the operation to the numerators.
Multiply Fractions:
a/b × c/d = (a × c) / (b × d)
Multiply the numerators together and denominators together.
Divide Fractions:
(a/b) ÷ (c/d) = (a × d) / (b × c)
Flip the second fraction (reciprocal) and multiply.
Example: To add 1/4 and 1/2, use the formula:
(1×2 + 1×4) / (4×2) = (2 + 4) / 8 = 6/8 = 3/4
