    Hint:

    Call the numbers x,y and z.

    You're given that:
    x=0.15z
    y=0.25z

    Hmm. Isn't it,
    x=1.15z
    y=1.25z :confused:

    And then:
    1.15z/1.25z=1.15/1.25=0.92=92%

    ???

    This is correct. Galileo, please read the question carefully.

    Pardon me curious! But where exactly was Galileo wrong?

    Assuming that z is the "third number" referenced in the first post, saying that x = 0,15z implies that x is 85% smaller than z...

    My mistake ... should read before the dots carefully ....
    Sincere apologies curious!
