    \[2/30 = 1/15\] The denominator (15) is half of the original (30) so the numerator (1) needs to be also half. Can you figure out the other one?

    Got a guess? If 2/30 = 1/15 then X/45 - got a guess for X?

    Close! You're almost there - 2/30 = 1/15 right? So now, if I need something over 45 to equal that...

    No, sorry - 4/60 = 2/30

    So knowing that, now you've got 4/60 = X/45 = 2/30 = 1/15... Leaving what number for X?

    It's three - to check if you divide both sides of the fraction 3/45 by three you get 1/15
