This was posted way back in January, so I guess the original point is now moot. However, there is another point worth bearing in mind.All the respondants so far have assumed (almost certainly correctly) that the original poster was referring to US weights and measures. However, she (assuming Raelynn is a female name) did not state that.
One US pint is indeed sixteen ounces, meaning that one pint of water weighs exactly one pound. However, the Imperial pint (which is used in Britain and Canada, and other places as well) is more than that -- or, as the old rhyme says (which, for obvious reasons, Americans wouldn't know): "A pint of pure water weighs a pound and a quarter".
Actually, there's a good example of converting between fractions and units: One quarter of a pound is... how many ounces? An Imperial pint is... how many ounces? (An Imperial pound is still 16 ounces, by the way.)
It's worth remembering that, in an international medium like the internet (and mathematics, in fact), you can't assume everyone uses the same units as you, unless you use only SI units. It's safe to assume that the original poster was talking about US pints, but only because we can assume that her teachers would be unlikely to ask her to express 7/8 of an Imperial pint as units.
The difference between US and Imperial pints was mostly felt by Canadians or Americans filling up their cars on the other side of the border: the Imperial gallon is bigger than the US gallon, because it's the same number of pints in each case -- but it's a different pint.
