Respuesta :

4/9 = 0.4 with a line over the 4 because it is repeating
4/10 = 0.4...same as 0.40
4/5 = 0.8

least to greatest : 4/10, 4/9, 4/5
Well first you have to find the common denominator for all of them so the common denominator should be 90 

So then 40/90, 36/90, 72/90
So here is the answer: 4/5, 4/9, 4/10
Hope this was a good answer :)     

And sorry it took me so long.
