  I understand fractions, I simply doubt their utility.

    Saying shit like that implies you don’t really get that they are the same thing.

    For example, they allow you to write

    1/3 + 1/3 + 1/3 = 1

    Which is not possible in decimal

      Tf you mean?? You can write it in a repeating decimal as 0.333… using ellipsis. wiki.froth.zone/wiki/Repeating_decimal

        So you think

        0.333… + 0.333… + 0.333… = 1

        Is that clearer and more concise?

        Fractional representation is the method for rational numbers, particularly if they are part of an intermediate calculation.

        Decimals are lossy, fractions aren’t.

      well, no, it’s understood that a third is .333 to infinity, so .333+.333+.333 does equal 1 for any use not requiring precision to the point of it mattering that it was actually .33333335 when measured.

        No. You wrote .333

        If you want to precisely write to infinity you write 1/3.

        actually .33333335

        Holy fuck. Where did that 5 come from?

    Hate to break it to you but anything less than a whole is a fraction of a whole thing. Decimals, too, are bits of a whole.
