How are numbers ranging from 120.1 to 120.4 treated in rounding?

• A. They round up to 121
• B. They remain unchanged
• C. They round down to 120
• D. They are discarded

Answer: (C)

When dealing with rounding numbers, the treatment of decimals is guided by specific rules. For numbers between 120.1 and 120.4, these decimals are considered to be less than halfway to the next whole number, which is 121. According to standard rounding rules, anything below .5 is typically rounded down to the nearest whole number. Therefore, numbers in the range of 120.1 to 120.4 would all round down to 120. This understanding is fundamental in rounding practices, as it ensures consistency and accuracy in numerical interpretations. In this case, rounding mechanics dictate that any decimal less than .5 leads to a decrease in value towards the nearest whole integer, confirming that the numbers in the specified range appropriately round down to 120.
