Answer:
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.
