Calculator Employ
Use this fraction calculator for adding, subtracting, multiplying and dividing fractions. Answers are fractions in lowest terms or mixed numbers in reduced form.
Input proper or improper fractions, select the math sign and click Calculate. This is a fraction figurer with steps shown in the solution.
If you lot take negative fractions insert a minus sign earlier the numerator. And so if one of your fractions is -6/seven, insert -6 in the numerator and 7 in the denominator.
Sometimes math problems include the word "of," every bit in What is ane/3 of 3/eight? Of means you should multiply so y'all need to solve 1/three × 3/eight.
To do math with mixed numbers (whole numbers and fractions) employ the Mixed Numbers Calculator.
Math on Fractions with Unlike Denominators
In that location are 2 cases where you need to know if your fractions have different denominators:
- if yous are calculation fractions
- if you are subtracting fractions
How to Add or Subtract Fractions
- Find the to the lowest degree common denominator
- You can use the LCD Estimator to notice the least common denominator for a set of fractions
- For your showtime fraction, detect what number you need to multiply the denominator by to result in the least common denominator
- Multiply the numerator and denominator of your first fraction by that number
- Repeat Steps 3 and 4 for each fraction
- For addition equations, add the fraction numerators
- For subtraction equations, decrease the fraction numerators
- Convert improper fractions to mixed numbers
- Reduce the fraction to lowest terms
How to Multiply Fractions
- Multiply all numerators together
- Multiply all denominators together
- Reduce the result to everyman terms
How to Separate Fractions
- Rewrite the equation as in "Keep, Change, Flip"
- Keep the kickoff fraction
- Modify the sectionalisation sign to multiplication
- Flip the 2nd fraction by switching the height and lesser numbers
- Multiply all numerators together
- Multiply all denominators together
- Reduce the result to lowest terms
Fraction Formulas
At that place is a style to add or subtract fractions without finding the least common denominator (LCD). This method involves cross multiplication of the fractions. Encounter the formulas below.
You may find that it is easier to utilise these formulas than to do the math to observe the least mutual denominator.
The formulas for multiplying and dividing fractions follow the same process as described in a higher place.
Adding Fractions
The formula for calculation fractions is:
\( \dfrac{a}{b} + \dfrac{c}{d} = \dfrac{ad + bc}{bd} \)
Example steps:
\( \dfrac{2}{vi} + \dfrac{i}{4} = \dfrac{(2\times4) + (half dozen\times1)}{6\times4} \)
\( = \dfrac{fourteen}{24} = \dfrac {vii}{12} \)
Subtracting Fractions
The formula for subtracting fractions is:
\( \dfrac{a}{b} - \dfrac{c}{d} = \dfrac{ad - bc}{bd} \)
Example steps:
\( \dfrac{2}{6} - \dfrac{i}{4} = \dfrac{(2\times4) - (vi\times1)}{6\times4} \)
\( = \dfrac{2}{24} = \dfrac {1}{12} \)
Multiplying Fractions
The formula for multiplying fractions is:
\( \dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{ac}{bd} \)
Example steps:
\( \dfrac{ii}{6} \times \dfrac{i}{4} = \dfrac{2\times1}{half-dozen\times4} \)
\( = \dfrac{2}{24} = \dfrac {1}{12} \)
Dividing Fractions
The formula for dividing fractions is:
\( \dfrac{a}{b} \div \dfrac{c}{d} = \dfrac{advertisement}{bc} \)
Instance steps:
\( \dfrac{2}{6} \div \dfrac{1}{4} = \dfrac{2\times4}{half-dozen\times1} \)
\( = \dfrac{8}{6} = \dfrac {four}{iii} = 1 \dfrac{1}{3} \)
