Fraction calculator



This fractions calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step information.

The result:

5/6 + 3/8 + 1/4 = 35/24 = 1 11/241.4583333

The spelled result in words is thirty-five twenty-fourths (or one and eleven twenty-fourths).

How do we solve fractions step by step?

  1. Add: 5/6 + 3/8 = 5 · 4/6 · 4 + 3 · 3/8 · 3 = 20/24 + 9/24 = 20 + 9/24 = 29/24
    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(6, 8) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 8 = 48. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - five sixths plus three eighths is twenty-nine twenty-fourths.
  2. Add: the result of step No. 1 + 1/4 = 29/24 + 1/4 = 29/24 + 1 · 6/4 · 6 = 29/24 + 6/24 = 29 + 6/24 = 35/24
    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(24, 4) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 24 × 4 = 96. In the following intermediate step, it cannot further simplify the fraction result by canceling.
    In other words - twenty-nine twenty-fourths plus one quarter is thirty-five twenty-fourths.

Rules for expressions with fractions:

Fractions - write a forward slash to separate the numerator and 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 whole part and fraction and use a forward slash to input fraction i.e., 1 2/3 . A negative mixed fraction write for example as -5 1/2.
A slash is both a sign for fraction line and division, use a colon (:) for division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal dot . 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.
