Rounding Decimals

Front

What is rounding in mathematics?

Back

Rounding is the process of adjusting the digits of a number to make it simpler or to make it easier to work with, while keeping its value close to what it was.

Front

What does it mean to round to the nearest tenth?

Back

Rounding to the nearest tenth means looking at the digit in the hundredths place to determine whether to round the tenths place up or keep it the same.

Front

How do you round the number 56.789 to the nearest tenth?

Back

Look at the hundredths place (8). Since it is 5 or greater, round the tenths place (7) up to 8, resulting in 56.8.

Front

What is the result of rounding 47.941 to the nearest tenth?

Back

The tenths place is 9, and the hundredths place is 4. Since 4 is less than 5, the tenths place remains 9, resulting in 47.9.

Front

How do you round 0.118 to the nearest tenth?

Back

The tenths place is 0, and the hundredths place is 1. Since 1 is less than 5, the tenths place remains 0, resulting in 0.1.

Front

What is the rule for rounding to the nearest hundredths?

Back

To round to the nearest hundredths, look at the thousandths place. If it is 5 or greater, round the hundredths place up; if it is less than 5, keep the hundredths place the same.

Front

Round 113.899 to the nearest hundredths.

Back

The hundredths place is 9, and the thousandths place is 9. Since 9 is greater than 5, round the hundredths place up to 10, resulting in 113.9.

Front

What does rounding to the nearest whole number involve?

Back

To round to the nearest whole number, look at the tenths place. If it is 5 or greater, round the whole number up; if it is less than 5, keep the whole number the same.

Front

How do you round 148.93 to the nearest tenth?

Back

The tenths place is 9, and the hundredths place is 3. Since 3 is less than 5, the tenths place remains 9, resulting in 148.9.

Front

What is the significance of rounding in real-life applications?

Back

Rounding is significant in real-life applications as it simplifies numbers for easier understanding and communication, especially in financial, scientific, and statistical contexts.
