## Glossary

Vocabulary Term | Definition |
---|---|

decimal | A dot that indicates "less than one." When reading a number with a decimal, read the decimal as "and." |

denominator | Expression in the bottom location of a fraction below the fraction bar. |

diameter | The distance from one edge of the circle to the opposite end through the center. |

dividend | The quantity that a number is divided into. The dividend is in the numerator of a fraction. |

divisor | The quantity by which a number is divided. The divisor is in the denominator of a fraction. |

fraction | A number expressed as a/b. |

greatest common factor | The highest number that can evenly divide into two numbers. |

improper fraction | A fraction in which the numerator is larger than the denominator. An example of an improper fraction is 20/4. |

invert | To reverse, or flip the order. When dividing fractions, you invert the denominator, or divisor, of the division problem. |

lowest common denominator | The smallest possible denominator that can be shared by two fractions. |

lowest terms | The lowest number that a numerator and denominator becomes when it is reduced by its greatest common factor. |

mixed number | A number that is a whole number and a fraction. An example of a mixed number is 4 3/5. |

numerator | Expression in the top location of a fraction, above the fraction bar. |

percent | A fraction in which the denominator is 100. |

place value | The location on the number grid where a digit appears in a number. Place values are expressed in values of ten. |

proportional | A relationship between two values that expresses equality. |

remainder | A number that is left over when a number does not divide evenly into another number. |

repeating decimal | A number or a pattern of numbers that appears in a decimal and continues to repeat with no end. |

rounding | A method used to shorten numbers. Rounding involves either increasing or decreasing a number to the next digit. |

whole number | A number that is 1 or greater with no fractions or decimals. |
