Rounding Decimals

Front

What is rounding in mathematics?

Back

Rounding is the process of adjusting the digits of a number to make it simpler while keeping its value close to what it was. It often involves increasing or decreasing the last digit based on the value of the digits that follow it.

What does it mean to round to the nearest hundredth?

Back

Rounding to the nearest hundredth means adjusting a number so that it has two decimal places. If the third decimal place is 5 or greater, the second decimal place is increased by one; if it is less than 5, the second decimal place remains the same.

How do you round the number 23.542 to the nearest hundredth?

Back

To round 23.542 to the nearest hundredth, look at the third decimal place (2). Since 2 is less than 5, you keep the second decimal place (4) the same, resulting in 23.54.

Front

What does it mean to round to the nearest one?

Back

Rounding to the nearest one means adjusting a number to the nearest whole number. If the decimal part is 0.5 or greater, the whole number is increased by one; if it is less than 0.5, it remains the same.

Front

How do you round the number 56.873 to the nearest one?

Back

To round 56.873 to the nearest one, look at the decimal part (0.873). Since it is greater than 0.5, you round up, resulting in 57.

Front

What is the rule for rounding to the nearest tenth?

Back

Rounding to the nearest tenth involves looking at the hundredths place. If the hundredths digit is 5 or greater, you increase the tenths digit by one; if it is less than 5, you keep the tenths digit the same.

Front

How do you round the number 4.073 to the nearest tenth?

Back

To round 4.073 to the nearest tenth, look at the hundredths place (7). Since 7 is greater than 5, you increase the tenths digit (0) by one, resulting in 4.1.

Front

How do you round the number 35.087 to the nearest tenth?

Back

To round 35.087 to the nearest tenth, look at the hundredths place (8). Since 8 is greater than 5, you increase the tenths digit (0) by one, resulting in 35.1.

Front

What is the significance of the digit 5 in rounding?

Back

The digit 5 serves as a threshold in rounding. If the digit to the right of the place value you are rounding to is 5 or greater, you round up; if it is less than 5, you round down.

Front

What is the difference between rounding up and rounding down?

Back

Rounding up means increasing the last retained digit by one, while rounding down means keeping the last retained digit the same.
