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:
15 6/25 - 11 5/10 = 187/50 = 3 37/50 = 3.74
Spelled result in words is one hundred eighty-seven fiftieths (or three and thirty-seven fiftieths).How do we solve fractions step by step?
- Conversion a mixed number 15 6/25 to a improper fraction: 15 6/25 = 15 6/25 = 15 · 25 + 6/25 = 375 + 6/25 = 381/25
To find a new numerator:
a) Multiply the whole number 15 by the denominator 25. Whole number 15 equally 15 * 25/25 = 375/25
b) Add the answer from the previous step 375 to the numerator 6. New numerator is 375 + 6 = 381
c) Write a previous answer (new numerator 381) over the denominator 25.
Fifteen and six twenty-fifths is three hundred eighty-one twenty-fifths. - Conversion a mixed number 11 5/10 to a improper fraction: 11 5/10 = 11 5/10 = 11 · 10 + 5/10 = 110 + 5/10 = 115/10
To find a new numerator:
a) Multiply the whole number 11 by the denominator 10. Whole number 11 equally 11 * 10/10 = 110/10
b) Add the answer from the previous step 110 to the numerator 5. New numerator is 110 + 5 = 115
c) Write a previous answer (new numerator 115) over the denominator 10.
Eleven and five tenths is one hundred fifteen tenths. - Subtract: 381/25 - 115/10 = 381 · 2/25 · 2 - 115 · 5/10 · 5 = 762/50 - 575/50 = 762 - 575/50 = 187/50
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(25, 10) = 50. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 25 × 10 = 250. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - three hundred eighty-one twenty-fifths minus one hundred fifteen tenths is one hundred eighty-seven fiftieths.
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.
