    Study Notes

    Converting Decimals to Fractions

    • To convert a decimal to a fraction, divide the decimal by 1, and then simplify the fraction.
    • For example, 0.5 = 5/10 = 1/2.

    Dividing Fractions

    • To divide fractions, invert the second fraction (i.e., flip the numerator and denominator) and then multiply.
    • For example, 1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6 = 2/3.

    Adding and Subtracting Decimals

    • When adding or subtracting decimals, first align the decimal points, then perform the operation.

    Place Value

    • The place value of the digit 4 in the decimal number 0.045 is thousandths.

    Comparing Decimals

    • To compare decimals, compare the digits from left to right, starting from the decimal point.

    Fractions

    • A fraction is a way to represent a part of a whole.
    • The three types of fractions are:
      • Proper fractions (numerator < denominator)
      • Improper fractions (numerator ≥ denominator)
      • Mixed fractions (combination of a whole number and a proper fraction)

    Equivalent Fractions

    • Equivalent fractions are fractions that have the same value, but different forms.
    • For example, 1/2 = 2/4 = 3/6.

    Like Fractions

    • Like fractions are fractions that have the same denominator.
    • For example, 1/4, 2/4, 3/4.

    Mixed Fractions to Improper Fractions

    • To convert a mixed fraction to an improper fraction, multiply the whole number part by the denominator and add the numerator.

    Adding and Subtracting Fractions with Different Denominators

    • To add or subtract fractions with different denominators, find the least common multiple (LCM) of the denominators, then convert each fraction to have the LCM as the denominator.

    Multiplying Fractions

    • To multiply fractions, multiply the numerators and multiply the denominators, then simplify the fraction.
