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:

43/9 - 27/9 = 14/9 = 1 5/9 ≅ 1.5555556

Spelled result in words is fourteen ninths (or one and five ninths).

How do we solve fractions step by step?

1. Conversion a mixed number 4 3/9 to a improper fraction: 4 3/9 = 4 3/9 = 4 · 9 + 3/9 = 36 + 3/9 = 39/9

To find a new numerator:
a) Multiply the whole number 4 by the denominator 9. Whole number 4 equally 4 * 9/9 = 36/9
b) Add the answer from the previous step 36 to the numerator 3. New numerator is 36 + 3 = 39
c) Write a previous answer (new numerator 39) over the denominator 9.

Four and three ninths is thirty-nine ninths.
2. Conversion a mixed number 2 7/9 to a improper fraction: 2 7/9 = 2 7/9 = 2 · 9 + 7/9 = 18 + 7/9 = 25/9

To find a new numerator:
a) Multiply the whole number 2 by the denominator 9. Whole number 2 equally 2 * 9/9 = 18/9
b) Add the answer from the previous step 18 to the numerator 7. New numerator is 18 + 7 = 25
c) Write a previous answer (new numerator 25) over the denominator 9.

Two and seven ninths is twenty-five ninths.
3. Subtract: 39/9 - 25/9 = 39 - 25/9 = 14/9
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(9, 9) = 9. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 9 = 81. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - thirty-nine ninths minus twenty-five ninths is fourteen ninths.

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.
