    • C.

      None of these

    Correct Answer
    B. 5.6
    Explanation
    To convert a mixed number into a decimal, we first multiply the whole number by the denominator of the fraction and then add the numerator. In this case, we multiply 5 by 5 (denominator of 3/5) and get 25. Then we add the numerator 3 to get 28. Finally, we divide 28 by the denominator 5 to get the decimal form, which is 5.6.

    Correct Answer
    A. True
    Explanation
    When adding or subtracting decimals, it is necessary to line up the decimal points in order to correctly calculate the result. This is because the decimal point represents the position of the fractional part of the number. By aligning the decimal points, we ensure that the corresponding digits in each decimal place are being added or subtracted accurately.

    Correct Answer

    Rate this question:

    Round 34.657 to the nearest tenths place.

    • A.

      34.7

    • B.

      34.66

    • C.

      None of these

    Correct Answer
    A. 34.7
    Explanation
    When rounding a number to the nearest tenth place, we look at the digit in the hundredth place. If it is 5 or greater, we round up. If it is less than 5, we round down. In this case, the digit in the hundredth place is 6, which is greater than 5. Therefore, we round up the digit in the tenths place, which is 4, to the next higher number, which is 7. So the correct answer is 34.7.
