Which set of rational numbers is arranged from least to greatest? how can i put this number for least to greatest 0.5,1/5,1/9,1

i would put all fractions into decimals so you'd have

1/5=0.2

and

1/9=0.1 repeating

so now you can order them

o.1..., 0.2, 0.5, 1

which equals to

1/9, 1/5, 0.5, and 1

so the answer is

1/9, 1/5, 0.5, and 1
