Q & A

  • What is a decimal fraction?

    -A decimal fraction is a fraction where the division is represented with a decimal point, often resulting from a regular fraction. For example, 1/10 can be expressed as 0.1.

  • How is 1/10 represented as a decimal fraction?

    -1/10 is represented as 0.1 in decimal form.

  • What does the digit before the decimal point represent in a decimal fraction?

    -The digit before the decimal point represents the whole number or unit part of the decimal.

  • What do the digits after the decimal point represent?

    -The digits after the decimal point represent fractional parts, such as tenths, hundredths, thousandths, and so on.

  • How would you convert 3/10 into a decimal fraction?

    -3/10 can be converted into a decimal fraction as 0.3.

  • How do you convert 14/100 into a decimal fraction?

    -To convert 14/100 into a decimal fraction, you write it as 0.14 because there are two digits after the decimal point.

  • Why does 8/100 convert to 0.08 as a decimal?

    -8/100 converts to 0.08 because, in a fraction over 100, there should be two digits after the decimal point. Since 8 is a single digit, a 0 is added before it to maintain the correct place value.

  • How do you write 23/100 as a decimal fraction?

    -23/100 is written as 0.23 in decimal form because there are two digits after the decimal point, representing hundredths.

  • What is the general rule for converting a fraction with a denominator of 10 or 100 to a decimal?

    -If the denominator is 10, the decimal will have one digit after the decimal point. If the denominator is 100, the decimal will have two digits after the decimal point.

  • What are the steps to convert a fraction to a decimal if the denominator is 10 or 100?

    -To convert a fraction with a denominator of 10 or 100 to a decimal: 1) Write down the numerator. 2) Place a decimal point in front, ensuring one digit after the decimal for denominators of 10, and two digits for denominators of 100.
