Rounding and Comparing Decimals Challenge

What is the first step in rounding decimals?

• Look at the digit to the right

• Underline the place you are rounding to

• Drop all digits after the place you are rounding to

• Increase the underlined digit by one

If the digit to the right of the place you are rounding to is between 0 and 4, what do you do?

• Drop all digits to the right

• Leave the underlined digit the same

• Increase the underlined digit by one

• Round up to the nearest whole number

In rounding decimals, what happens to digits after the rounding point?

• They are converted to zeros

• They are dropped

• They are rounded up

• They remain unchanged

When rounding to the nearest hundredth, what happens if the digit in the hundredth place is 9 and the next digit tells it to increase?

• The number stays the same

• The number is rounded up and the hundredth place changes accordingly

• The number is rounded down

• The hundredth place increases to 10

What does rounding to the nearest cent imply?

• Rounding to two places after the decimal

• Rounding to the nearest whole number

• Rounding to the nearest ten

• Ignoring the decimal part

What does rounding to the nearest dollar mean?

• Rounding to the nearest whole number

• Rounding to the nearest tenth

• Rounding to three places after the decimal

• Rounding to the nearest hundredth

What is the importance of lining up decimals when comparing them?

• It helps in identifying the largest decimal

• It makes it easier to compare the whole number part

• It is not necessary for comparison

• It ensures accurate comparison by aligning decimal places

What should you do if the numbers have different numbers of places after the decimal when comparing?

• Ignore the extra places

• Annex zeros to make the number of places equal

• Only compare the whole number part

• Round all numbers to the nearest whole number

How do you determine the order when comparing decimals?

• By annexing zeros to the whole number part

• By comparing the whole number part first

• By comparing the decimal part first

• By the number of decimal places

When comparing decimals, what is the purpose of annexing zeros?

• To decrease the value of the decimal

• To increase the value of the decimal

• To make comparison easier by having the same number of decimal places

• To change the whole number part
