You posted the same question about "3" and I will give the same answer here: it depends upon specifically which definition of "decimal fraction" you are using. The Wikipedia definition I posted before would say "no, -0,5 is not a decimal fraction" but not because it is negative. That definition would say that "-0,5" is not a fraction because it is not a fraction but that -5/10, which is just a different way of writing -0,5, is a decimal fraction.also aDecimal Fractions
what about -0,5 is it a normal Fraction ?
i really don't know because it is negative
(-0,5 is a Decimal Fraction)
