Fractions are an important component of the ORIGO curricula.

(For Spanish, see fracción.)

Common fraction

A common fraction is a fraction numeral written using common fraction notation: numerator over denominator separated by a horizontal (and not diagonal) vinculum. When writing fractions out in words, always hyphenate as follows: one-half, two-quarters, fifty-one hundredths, twenty-nine thousandths.

Decimal fraction

A decimal fraction is one in which the the denominator is a power of 10. These are usually represented using decimal notation: 10.3, 9.227. Always use a full-stop (period), and never a comma, in decimal notation. As with common fractions, always hyphenate when writing decimal fractions out in words.

Mixed number

A way of writing a number that includes a value greater than one, plus a fraction less than one: Four and two-sevenths.

Improper fraction

The term for a fraction whose numerator is greater than its denominator. It, like mixed numbers, is a way of writing a fraction with a value greater than one.
