Question

If rounded to the nearest dime, what is the greatest amount of money the rounds to $105.40? What is the least amount of money that rounds to $105.40? Explain your answer

Answer 1

The answer is: the least amount is 105.35 and the greatest amount is 105.44. If the number after the one you want to round is 5 or bigger, you need to round up the number. For instance, 105.35 is rounded to 105.4 which is equal to 105.40. If the number after the one you want to round is smaller than 5, you need to round down the number. For instance, 105.44 is rounded to 105.4 which is equal to 105.40.
