4. Introduction to Fractions Flashcards
Define “Denominator”
- The bottom number in a fraction
What does the Denominator represent?
- How many parts are in the whole
Define “Equivalent Fractions”
- Any 2 fractions that have different numerators and denominators but represent the same amount
Define “Fraction”
- A part of a whole number
Define “Improper Fraction”
- A fraction whose numerator is larger than its denominator
Define “Mixed Number”
- A whole number that is combined with a fraction
Define “Numerator”
- The top number of a fraction
What does the numerator represent?
- How many parts we have of the whole
Define “Reducing”
- Making the numerator and the denominator the lowest numbers they can be with no common factors
How do you convert a mixed number to an improper fraction?
- Multiply the whole number by the denominator and add the numerator
How do you convert an improper fraction to a mixed number?
- Divide the fraction, making the quotient the whole number, the remainder as the numerator, and keep the divisor as the denominator
What is the first step to determine which fraction is larger than another?
- Cross multiply
How do you cross multiply?
- Multiply the numerator of one fraction by the denominator of the other, and vice versa
What is the 2nd step to determine which fraction is larger than another?
- Verify which numerator multiplied to create the larger product. The fraction with that numerator is the larger fraction
What is the most common mistake when cross multiplying?
- Multiplying the numerators or denominators together, instead of the numerators of one withe the denominators of another
What is the most common mistake when writing a mixed number?
- Not placing the divisor in the denominator and the remainder in the numerator
What is the same about a mixed number and its equivalent improper fraction?
- They both will always have the same denominator
