    Place values is important in Rounding Decimals. - ProProfs

    Place values is important in Rounding Decimals.

    • Not sure

    • True

    • False

    • A little

    Correct Answer
    A. True
    Explanation
    Place values are indeed important in rounding decimals. When rounding decimals, we look at the digit to the right of the desired decimal place. If this digit is 5 or greater, we round up, and if it is less than 5, we round down. The place value of the digit being rounded affects the rounding process, as it determines which digit will be affected by the rounding. Therefore, understanding place values is crucial in accurately rounding decimals.

    Rounding 0.843 to the nearest tenth would give ....? - ProProfs

    Rounding 0.843 to the nearest tenth would give ....?

    • 0.8

    • 0.6

    • 1.2

    • 0.4

    Correct Answer
    A. 0.8
    Explanation
    Rounding 0.843 to the nearest tenth involves looking at the digit in the hundredth place, which is 4. Since 4 is less than 5, we do not need to round up. Therefore, the digit in the tenths place remains the same, which is 0. Hence, rounding 0.843 to the nearest tenth gives us 0.8.

    If the hundredths and thousandths places are fifty or more, the tenths place is increased by one. The decimal 0.866 rounded to the nearest tenth is ....? - ProProfs

    If the hundredths and thousandths places are fifty or more, the tenths place is increased by one. The decimal 0.866 rounded to the nearest tenth is ....?

    • 0.8

    • 0.9

    • 0.6

    • 0.4

    Correct Answer
    A. 0.9
    Explanation
    When rounding to the nearest tenth, we look at the hundredths place. In this case, the hundredths place is 6, which is greater than 5. According to the given rule, if the hundredths place is 5 or more, we increase the tenths place by one. Therefore, the tenths place, which is currently 8, is increased to 9. Thus, the decimal 0.866 rounded to the nearest tenth is 0.9.

    To round a number to the nearest tenth, look at the next place value to ....? - ProProfs

    To round a number to the nearest tenth, look at the next place value to ....?

    • The tenths

    • The hundredths

    • The thousandths

    • The ten thousandths

    Correct Answer
    A. The hundredths
    Explanation
    To round a number to the nearest tenth, we need to look at the next place value, which is the hundredths. This means that we need to examine the digit in the hundredths place to determine whether to round up or down. If the digit in the hundredths place is 5 or greater, we round up. If it is less than 5, we round down.

    To round a number to the nearest hundredth , look at the next place value to .....? - ProProfs

    To round a number to the nearest hundredth , look at the next place value to .....?

    • The thousandths

    • The hundredths

    • The tenths

    • The ten thousandths

    Correct Answer
    A. The thousandths
    Explanation
    To round a number to the nearest hundredth, we need to look at the next place value, which is the thousandths. The thousandths place tells us the value of the third decimal place. By examining the value in the thousandths place, we can determine whether to round up or down the hundredths place.

    In general, to round to a certain place value, look at the digit to the ..... of that place value and make a decision. - ProProfs

    In general, to round to a certain place value, look at the digit to the ..... of that place value and make a decision.

    • Top

    • Left

    • Middle

    • Right

    Correct Answer
    A. Right
    Explanation
    To round to a certain place value, we need to look at the digit to the right of that place value. This is because the digit to the right determines whether we round up or down. If the digit to the right is 5 or greater, we round up. If it is less than 5, we round down. Therefore, the correct answer is "right".
