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.
