    Assuming that they start the 10 and 2 years on the same year

    one way is to find the least common multipule by listing factors and including all of them

    10=2 times 5

    2=2

    we need to have at leas 1 2 and 1 5

    the answer is 10

    every 10 years is the answer

    another way is to list them

    exg they started at 2000

    socker reunion

    2002 2000

    2004

    2006

    2008

    2010 2010

    the answe ris every 10 years
