3 G Math

posted by .

How do I answer this......Barry says 9x8x(any other number) will always be greater than the product of 2x9x4. Do you agree? Explain?

  • 3 G Math -

    "any number" can be negative

  • 3 G Math -

    9 x 8 x any number = 72 x any number
    2 x 9 x 4 = 72

    the second one the FINAL answer is 72
    the first one will be higher
    if you multiply 72 by any other number but 1, because 72 x 1 = 72, then they will be equal

    but if any number is greater than 1, then the first will be higher

    I hope you can understand

    but ....
    what if the "any other number " is a proper fraction?

    so the "any other number" has to be > 1
