  • A few brain teasers for you.....

    Brain Teaser:

    Professor Boffin has discovered an exciting mathematical phenoomena concerning fractions with digits under 100. If he cancels identical digits above and below the line, the fraction is still correct (Keeps the same decimal value).

    Can you find three other fractions of which this is true ?

    Example:

    16/64 = 1/4 = (remove the 6's) 1/4 = 1/4

    The identical numbers you remove should be diagonal to each other - Thx for Firefly for spotting this mistake.

    Any also dont give me this as a result: 33/33 = 3/3 - anyone can do that.

    You try!

    Please submit solutions by PM and I will Add you name here when you get it right:

        Ok so what about 10/50 = 1/5? Is that also illegal?

        And nuno, don't think I didn't see the post you deleted with a wrong solution.

            I added something to the original post - the numbers you remove must be diagonal to each other.

            Dont forget - dont post your solutions here. PM them.

                      I was wondering what would be quicker, write each one down or write a quick PHP program to work it out instead.... i guess you choose former
