### Carnegie Rational Numbers - Fractions

Question | Answer |
---|---|

fraction | Represents a part of a whole object, set, or unit. Written using two whole numbers separated by a bar. |

numerator | The number above the fraction bar. It indicates how many parts in the whole are counted. |

denominator | The number below the fraction bar. It indicates how many parts make up the whole. |

unit fraction | This has a numerator of 1 and a denominator that is a positive integer greater than 1. |

equivalent fractions | These represent the same whole |

benchmark fractions | Common ones that are used to estimate how much others are. An example is 1/2. |

inequality | Any mathematical sentence that shows a comparison. |

simplest form | A way of writing a fraction so that the numerator and the denominator have no common factors other than 1. |

Multiplicative Identity Property | This states that a X 1 = a, where a is a nonzero number. |

common denominator | a whole number that is a common multiple of the denominators of two or more fractions. |

least common denominator (LCD) | The least common multiple of the denominators of two or more fractions. |

mixed number | This has a whole number part and a fraction part. |

improper fraction | A fraction in which the numerator is greater than or equal to the denominator. |

reciprocal | This is also known as the multiplicative inverse of the number. |

Multiplicative Inverse Property | This states that a/b X b/a = 1, where a and b are nonzero numbers. |

multiplicative inverse | This means that for the fraction a/b this would be b/a, where a and b are nonzero numbers. The product of these two fractions is 1. |
