In questions like these, arranging them in increasing order is from smallest to largest.
8.008 is the lowest number in the first one, because the more zeroes after the decimal point, the smaller it is.
The first one is 8.008, 8.08, 8.081, 8.09
The second one is 14.200, 14.204, 14.210, 14.240
Hope this helps :)
