I’m order to tell whether a number is less than another, take a look at the place farthest to the left on each number, determine if it’s less or more, and continue the process with the next place over— if that makes sense.
In this case, we would start with the numbers in tenths place.
Since 0.2=0.2, we need to move over a place.
Since 0.09=0.09, we need to move over again.
Since 0.003>0.000, we can conclude that 0.293>0.29.
