Answer :
In order to round numbers you must understand the rules for rounds. When looking at a number and deciding whether or not to round up or down, you must look at the number to the right of the target number. Numbers which are four or less round down. Numbers five or more round up to the next value. In the number 5,370,288 the target number is in the hundrend thousands place, it is three. Right of the three is a seven. Following the rule, that means we must round up, changing the 3 to a four and all numbers following it to the right must be made zeroes. Your final answer will be 5,400,000.
