### Equivalent Fractions

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

What are the 4 basic operations in arithmetic? | addition, subtraction, multiplication, division |

Arithmetic has how many basic operations? | 4 |

2 x 3 = 6 What do we call the numbers "2" and "3"? | Factors |

2 x 3 = 6 What is the number 6 called? | a multiple |

Multiplying two factors gives you a multiple. True or False | True |

4 x __ = 12 In this problem one of the factors is missing. What can you do to find the missing factor? | You divide the multiple by the given factor. In this case we divide the multiple 12 by the factor 4. |

___ x 4 = 20 How do you go about finding a missing factor in a problem? | You need to have at least on factor and the multiple. Then divide the multiple by the factor. |

___ x 4 = 20 What is missing – a factor or the multiple? | a Factor |

___ x 4 = 20 How do we find the missing factor? | We divide the multiple by the one factor. |

Remember, when you multiply two factors the multiple is always a (larger or smaller) number. | larger Ex. 5 x 4 = 20 |

6 x 4 = 24 The multiple is always larger than either __________. | factor |

1/2 x 2/2 = 2/4 2/4 x 2/2 = 4/8 4/8 x 2/2 = 8/16 Is 1/2, 2/4, 4/8, and 8/16 equivalent fractions? Why? | Yes |

The word equivalent means that the fractions are ________ to each other. | equal In other words, they have the same value. |

Could you say that equivalent fractions have the same value. | Yes |

If you gave one person a 1/2 of pizza and another person 2/4 of a pizza would both have the same amount of pizza. | Yes |

Remember, If you multiply the numerator and denominator by the same number, you get an equivalent fraction. True or False | True |

1/2 = 8/16 These two fractions are equivalent. Which fraction has the smaller numerator and denominator? | 1/2 |

1/2 = 8/16 Remember, when comparing equivalent fractions one fraction has a smaller numerator and denominator than the other fraction. It is this smaller fraction that is multiplied in order to get the larger factions. True of False | True |

Remember we multiply the smaller equivalent fraction to get the larger equivalent fractions. We multiplied 1/2 by 2/2 to get 2/4. True or False | True |
