0.43, 0.431, 3.41, 4.31, 43.1

Answer explanation

Eliminate one of the answers because it has a 7 in it and there is no 7 in the original set of numbers.

Eliminate another, because it lists the numbers greatest to least, and the directions say least to greatest.

Eliminate another answer because it has a whole number first.
