Order this starting from the smallest:
15.249 15.3 15.05 15.009 15.25

15.009
15.05
15.249
15.25
15.3

I believe is the correct order

I think it might be easier to understand if i change decimals to fractions, so lets start ;)
\( 15.249=15\frac{249}{1000} \)
\( 15.3=15.300=15\frac{300}{1000} \)
\( 15.05=15.050=15\frac{50}{1000} \)
\( 15.009=15\frac{9}{1000} \)
\( 15.25=15.250=15\frac{250}{1000} \)

denominators are the same so now you only have to compare numerators (biger numerator = greater fraction)

so:

\( 15\frac{9}{1000}<15\frac{50}{1000}<15\frac{249}{1000}<15\frac{250}{1000}<15\frac{300}{1000} \)

it means that:


\( 15.009<15.05<15.249<15.25<5.3 \)
