Answer:
Explanation:
There are many real-world situations in which it might be useful to round a number. Here are a few examples:
- When making calculations for financial planning or budgeting, it can be helpful to round numbers to the nearest whole number or to the nearest increment (such as $5 or $10). This can make the numbers easier to work with and can help to avoid making small mistakes due to minor variations in the decimal place.
- In scientific or medical research, it is often necessary to round numbers to a specific number of decimal places in order to present the data clearly and accurately. For example, a study might report that the average weight of a sample group is 73.5 kilograms, rounded to one decimal place.
- When working with large numbers, it can be helpful to round to the nearest multiple of 10, 100, or 1000 in order to make the numbers easier to read and understand. For example, if the population of a city is 789,456, rounding to the nearest 100,000 would give us an estimate of "800,000 people."
- When making measurements, it is often necessary to round to the nearest whole unit of measurement. For example, if you are measuring the length of a room in inches and your measurement comes out to be 11.6 inches, it is more accurate to say that the room is "12 inches long" than to give the exact measurement of 11.6 inches.
These are just a few examples of situations in which rounding numbers might be useful. There are likely many other situations in which rounding numbers would be helpful as well.
