Study Notes
Types of Fractions
- Common fractions include proper fractions, improper fractions, and mixed numbers.
- Proper fractions have numerators smaller than their denominators, while improper fractions have larger numerators.
Adding Numbers and Fractions
- The first step in adding numbers and fractions is to convert the whole number into a fraction with a common denominator.
Least Common Multiple
- The least common multiple (LCM) of 1 and any number is the number itself, as any number is a multiple of one.
Co-prime Numbers
- Two numbers are called co-prime if their greatest common divisor (GCD) is 1, meaning they share no common factors other than 1.
Adding Fractions with Co-prime Denominators
- After finding the common denominator, the next step in adding fractions is to adjust the numerators accordingly and then sum them.
Shaded Figure Representation
- The fraction that represents the shaded figure depends on the total parts of the figure and the number of shaded parts.
Missing Value Equation
- The missing value in the equation 1/2 of 36 is 18.
Like Fractions
- Like fractions have the same denominator, making them easier to add and subtract.
Proper Fractions
- Proper fractions are those where the numerator is less than the denominator.
Mixed Fraction Equivalent
- The mixed fraction equivalent to 9/4 is 2 1/4, as it includes 2 whole parts and 1/4 of another part.
