Question

Order this starting from the smallest:

Answer 1

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:

$15\frac{9}{1000}$

it means that:


$15.009$

Answer 2

15.009
15.05
15.249
15.25
15.3

I believe is the correct order
