Fraction calculator
This fraction calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression.
The result:
9 3/5 - 7 7/15 = 32/15 = 2 2/15 ≅ 2.1333333
Spelled result in words is thirty-two fifteenths (or two and two fifteenths).How do we solve fractions step by step?
- Conversion a mixed number 9 3/5 to a improper fraction: 9 3/5 = 9 3/5 = 9 · 5 + 3/5 = 45 + 3/5 = 48/5
To find a new numerator:
a) Multiply the whole number 9 by the denominator 5. Whole number 9 equally 9 * 5/5 = 45/5
b) Add the answer from the previous step 45 to the numerator 3. New numerator is 45 + 3 = 48
c) Write a previous answer (new numerator 48) over the denominator 5.
Nine and three fifths is forty-eight fifths. - Conversion a mixed number 7 7/15 to a improper fraction: 7 7/15 = 7 7/15 = 7 · 15 + 7/15 = 105 + 7/15 = 112/15
To find a new numerator:
a) Multiply the whole number 7 by the denominator 15. Whole number 7 equally 7 * 15/15 = 105/15
b) Add the answer from the previous step 105 to the numerator 7. New numerator is 105 + 7 = 112
c) Write a previous answer (new numerator 112) over the denominator 15.
Seven and seven fifteenths is one hundred twelve fifteenths. - Subtract: 48/5 - 112/15 = 48 · 3/5 · 3 - 112/15 = 144/15 - 112/15 = 144 - 112/15 = 32/15
It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 15) = 15. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 15 = 75. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - forty-eight fifths minus one hundred twelve fifteenths is thirty-two fifteenths.
Rules for expressions with fractions:
Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.Mixed numerals (mixed numbers or fractions) keep one space between the integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both sign for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations. The most common mnemonics for remembering this order of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.
Be careful; always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) have the same priority and must be evaluated from left to right.
