Question

As of 01 January 2017, Delta mainline aircraft fly to 233 destinations; when combined with its Delta Connection regional affiliates, Delta-flagged aircraft fly to a total of 320 destinations serving 57 countries across all six inhabited continents. Delta operates a fleet of 764 aircraft within 4,804 flights per day. Round the number of aircraft to the nearest hundred

Answer 1

When we are rounding a number to the nearest hundred we need to check the tens. If the tens algarism is greater or equal to 5, then we round up and if it is lower than that we round down.

Delta operates a fleet of 764 aircrafts. The tens on this number is the algarism "6", therefore we should round up. Delta operates approximately 800 aircrafts.
