is there a common multipple for 116, and 145? Can 116/145 be reduced or simplified? I have been agonizing for an hour over this. Please show me the answer.

  • math -

    There is always a common multiple, the product of the two numbers.
    However look for a smaller one by factoring each.
    116 = 2*58 = 2*2*29
    145 = 5*29
    so we need
    29 and 5 and 2 and 2
    = 580
    580/116 = 5
    580/145 = 4 good
    Well, we already know we can divide top and bottom of the fraction by 29 to simplify it.
