You can choose to put all the numbers into decimals or fractions.
In this case, I will put the numbers all in decimals.
We already have 2.07, -2.67, and 2.67
in a decimal is 2.7 because 7 is in the 'tenths' place and ten was our denominator
So all of our numbers are 2.7 2.01 2.67 and -2.67
Obviously a negative number will be last and you can line the other numbers to see which is the greatest
2.67
2.70 (if there is nothing there we can always put a zero)
2.01
So the first digit is all 2 so we look at the next digits which are 6, 7, and 0
You should know how to order those numbers, so do the same here.
-2.67, 2.01, 2.67
(we had to change it back to a fraction)
Hope that helped :)
