How to Calculate Fractions
Fractions can be added, subtracted, multiplied and divided using
different mathematical methods. The method depends on the operation
being performed.
Adding and Subtracting Fractions
To add or subtract fractions with the same denominator, keep the
denominator and add or subtract the numerators. When the denominators
are different, first convert the fractions to equivalent fractions
with a common denominator.
For example, 1/4 + 2/4 = 3/4. For fractions with different
denominators, a common denominator is needed before performing the
addition or subtraction.
Multiplying Fractions
To multiply fractions, multiply the first numerator by the second
numerator and the first denominator by the second denominator.
The resulting fraction can then be simplified.
For example, 2/3 × 3/4 = 6/12, which simplifies to 1/2.
Dividing Fractions
To divide one fraction by another, multiply the first fraction by the
reciprocal of the second fraction. The resulting fraction should then
be simplified to its lowest terms.
For example, 1/2 ÷ 1/4 = 1/2 × 4/1 = 2.
Simplifying Fractions
A simplified fraction is written in its lowest terms. This means the
numerator and denominator do not have a common factor greater than 1.
The calculator automatically simplifies the final result.
Common Uses of Fractions
Fractions are commonly used in mathematics, school assignments,
measurements, recipes, proportions, construction, finance and many
everyday calculations. A fraction calculator can help check results
and reduce the amount of manual calculation required.
