To order these from least to greatest, it would be helpful to convert all numbers into decimals
250% into a decimal is just 250 divided by 100
250/100 = 2.5
so 250% is really 2.5
Now we have 1.25, 0.51 and 2.5
The term “least to greatest” refers to the smallest number being placed first, in ascending order to the largest number, placed last
Anything that is a decimal with a zero infront of it is smaller than 1
The smallest number between the three would be .51, the second smallest would be 1.25, and the largest being 2.5
Therefore, the answer to your question would be as follows, .51, 1.25, 250%
I hope this helps! <3
