Since 2.738 is only one decimal place more then 2 decimal places, the main numbers that we are going to be looking at are 2.7
38
.
Now, we are going to have to round that 3 in the 38
. To do that, you must look at the 8
, and see if it is larger then 5, or less than 5. Since it is larger than, you can round the 38 up to 40
. So now the number you have is 2.740
, but since the 0 does not need to be included, you have 2.74
, which is 2 decimal places.
