so first, we know negatives are the least. comparing, -2 and -2.1, we can obviously see that -2.1 comes first
so we have -2.1, -2
then, the positives. you have 2.1, 2, and 2 1/11 first we know 2 is the least of them. so now we just need to figure out if 2.1 is greater than or less than 2 1/11. we can convert the decimal to a fraction. so 2.1 is 2 1/10 and 1/10 is greater than 1/11. so it goes 2, 2 1/11, 2.1
then putting it all together: -2.1, -2, 2, 2 1/11, 2.1
