What is the correct increasing order of U-235 (fissile uranium) ratio in following?

Ranked by fissile uranium share, raw ore is lowest, then natural uranium, then reactor grade, with weapon grade highest.

Statement 2, uranium ore, holds the least fissile uranium as it is diluted with surrounding rock.

Statement 1, natural uranium, contains about zero point seven percent of the fissile isotope.

Statement 4, reactor grade, is enriched to roughly three to five percent.

Statement 3, weapon grade, is enriched above ninety percent fissile uranium.

Enrichment raises the fissile share by separating the lighter isotope from the heavier one.
