2
Q
What does the Denominator represent?
A
- How many parts are in the whole
3
Q
Define “Equivalent Fractions”
A
- Any 2 fractions that have different numerators and denominators but represent the same amount
4
Q
Define “Fraction”
A
- A part of a whole number
5
Q
Define “Improper Fraction”
A
- A fraction whose numerator is larger than its denominator
6
Q
Define “Mixed Number”

- A whole number that is combined with a fraction
7
Q

A
- The top number of a fraction
8

What is the 2nd step to determine which fraction is larger than another?
A
- Verify which numerator multiplied to create the larger product. The fraction with that numerator is the larger fraction
15
Q
What is the most common mistake when cross multiplying?
A
- Multiplying the numerators or denominators together, instead of the numerators of one withe the denominators of another
