e) 25 Ã— 36 = f) 12 Ã— 14 =

**Answer : **
Guess the answer on your own.

a) Split the numbers and multiply as:

42 = 40 + 2, and 23 = 20 + 3

40 | 2 | |
---|---|---|

20 | 40 Ã— 20 = 800 | 2 Ã— 20 = 40 |

3 | 40 Ã— 3 = 120 | 2 Ã— 3 = 6 |

Total=800+120= 920 | Total = 46 |

920 + 46 = 966

Therefore, 42 Ã— 23 = 966

b) Split the numbers and multiply as:

73 = 70 + 3, and 11 = 10 + 1

70 | 3 | |
---|---|---|

10 | 70 Ã— 10 = 700 | 3 Ã— 10 = 30 |

1 | 70 Ã— 1 = 70 | 3 Ã— 1 = 3 |

Total=700 + 70= 770 | Total = 33 |

770 + 33 = 803

Therefore, 73 Ã— 11 = 803

c) Split the numbers and multiply as:

51 = 50 + 1, and 13 = 10 + 3

50 | 1 | |
---|---|---|

10 | 50 Ã— 10 = 500 | 1 Ã— 10 = 10 |

3 | 50 Ã— 3 = 150 | 1 Ã— 3 = 3 |

Total=500+150= 650 | Total = 13 |

650 + 13 = 663

Therefore, 51 Ã— 13 = 663

d) Split the numbers and multiply as:

54 = 50 + 4, and 12 = 10 + 2

50 | 4 | |
---|---|---|

10 | 50 Ã— 10 = 500 | 4 Ã— 10 = 40 |

2 | 50 Ã— 2 = 100 | 4 Ã— 2 = 8 |

Total=500+100= 600 | Total = 48 |

600 + 48 = 648

Therefore, 54 Ã— 12 = 648

e) Split the numbers and multiply as:

25 = 20 + 5 and 36 = 30 + 6

10 | 5 | |
---|---|---|

30 | 20 Ã— 30 = 600 | 5 Ã— 30 = 150 |

6 | 20 Ã— 6 = 120 | 5 Ã— 6 = 30 |

Total=600+120= 720 | Total =150 + 30=180 |

720 + 180 = 900

Therefore, 25 Ã— 36 = 900

f) Split the numbers and multiply as:

12 = 10 + 2 and 14 = 10 + 4

10 | 2 | |
---|---|---|

10 | 110 Ã— 10 = 100 | 2 Ã— 10 = 20 |

4 | 10 Ã— 4 = 40 | 2 Ã— 4 = 8 |

Total=100 + 40= 140 | Total = 28 |

So, 140 + 28 = 168

Therefore, 12 Ã— 14 = 168
