Rounding Decimals Concepts

The video tutorial introduces the concept of rounding decimals, starting with rounding to the nearest whole number. It explains the steps involved, such as checking the digit in the tens place and adjusting the whole number accordingly. The tutorial then moves on to rounding decimals to the nearest tenth, detailing the process of examining the digit to the right of the tens place and making necessary adjustments. Examples are provided for both rounding methods to reinforce understanding.

What is the first step in rounding a decimal to the nearest whole number?

• Look at the digit in the thousandths place.

• Look at the digit in the hundreds place.

• Look at the digit in the tens place.

• Look at the digit in the units place.

If the digit in the tens place is 6, what should you do to round to the nearest whole number?

• Subtract one from the whole number.

• Add one to the whole number.

• Keep the whole number as it is.

• Multiply the whole number by two.

In the example given, what was the rounded whole number for 92.5?

• 94.0

• 91.0

• 92.0

• 93.0

What is the first step in rounding a decimal to the nearest tenth?

• Look at the digit in the hundreds place.

• Look at the digit to the right of the tens place.

• Look at the digit in the units place.

• Look at the digit in the thousandths place.

If the digit to the right of the tens place is 3, what should you do to round to the nearest tenth?

• Add one to the digit in the tens place.

• Keep the digit in the tens place as it is.

• Subtract one from the digit in the tens place.

• Multiply the digit in the tens place by two.

In the example given, what was the rounded number for 21.74 to the nearest tenth?

• 21.7

• 21.8

• 21.9

• 21.6

What happens to the digits after the decimal point when rounding to the nearest tenth?

• They are doubled.

• They are changed to zero.

• They are halved.

• They remain unchanged.

What is the rounded number for 94.17 to the nearest tenth?

• 94.1

• 94.3

• 94.2

• 94.0

What is the rule for rounding when the digit is exactly 5?

• Multiply the previous digit by two.

• Subtract one from the previous digit.

• Add one to the previous digit.

• Keep the previous digit as it is.

What is the final step in rounding decimals?

• Add one to all digits.

• Change all digits to the right of the rounding place to zero.

• Subtract one from all digits.

• Multiply all digits by two.
