You cannot simplify fifths because it is a prime number. Prime numbers are only divisible by 1 and itself.
Answer:
Wikipedia defines polynomials as "<em>an expression consisting of variables and coefficients</em>."
You would think that F(x) would not be a polynomial, but you could think of it like this:
F(x) = 0x + 1050
So, yes, I suppose constant terms by themselves are polynomials, it's just that they only have one term and would not really be called a <em>poly</em>-nomial.
You should probably research some more just in case.
Answer:
The fractional equivalent of the repeating decimal would be 15/99 and 0.1515... is a repeating decimal so it doesn't end, but in the shown number is 4 digits.
