0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.

\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000

14.603 rounded to the nearest hundred
kakasveta [241]
The nearest hundred would be 0 since the hundreds place is three digits to the left of the decimal point. However, I think you might mean "nearest hundredths" which would refer to the place two digits to the right of the decimal point.

The nearest hundredths is 14.60
