.725 , .572 , .275, .2
You look at the first decimal place to see which is the greatest. 7 is greater than 5 and 2 so it's first. Then 5 is greater than 2 so it is next. For the last two numbers since 2 is the same value you look at the next decimal place. Since 7 is greater than 0 it comes next!
It would be 11 if I’m reading this right
162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.
