What is the process of limiting a number to fewer decimal places called?

• A. Cutting
• B. Truncating
• C. Rounding
• D. Estimating

Answer: (C)

The process of limiting a number to fewer decimal places is known as rounding. Rounding adjusts the value of a number to make it simpler and easier to work with while maintaining a value that is close to the original number. This typically involves looking at the digit in the next decimal place to decide whether to round up or down. For example, if you have the number 3.76 and wish to round it to one decimal place, you would look at the second decimal place (6) and determine that since it is 5 or higher, you round up to 3.8.

Rounding is commonly used in various contexts, from everyday math to scientific calculations, to provide an approximate value that is easier to handle. The other processes mentioned, such as truncating, refer to different methods of limiting decimal places without adjusting the number based on rounding rules. Truncating simply cuts off the extra digits without rounding, while estimating provides a rough approximation that doesn’t adhere strictly to decimal places.
