    • 10.5

    • 105

    • None of these

    Correct Answer
    A. 105
    Explanation
    When dividing 5.25 by 0.05, we can think of it as moving the decimal point two places to the right in both numbers. This gives us 525 divided by 5, which equals 105. Therefore, the correct answer is 105.

    • 5.6

    • None of these

    Correct Answer
    A. 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.

  • 7.

    • 34.7

    • 34.66

    • 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.
