TermDefinitionExample
Mixed NumberA number made up of a whole number and a proper fraction (where the numerator is smaller than the denominator).$2\frac{1}{2}$ (two and one-half)
Improper FractionA fraction where the numerator (top number) is greater than or equal to the denominator (bottom number).$\frac{5}{2}$ (five-halves)
Whole NumberThe integer part of a mixed number, representing full units or wholes.In $3\frac{1}{4}$, the whole number is 3.
NumeratorThe top number in a fraction, which tells you how many parts of the whole you have.In $\frac{7}{3}$, the numerator is 7.
DenominatorThe bottom number in a fraction, which tells you how many equal parts the whole is divided into.In $\frac{7}{3}$, the denominator is 3.
MultiplicationA mathematical operation that involves repeated addition...

Core Formulas
The Conversion Rule: Mixed to Improper Fraction
$\text{Improper Fraction} = \frac{(\text{Whole Number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}}$
To convert a mixed number to an improper fraction, you multiply the whole number by the denominator, then add the original numerator to that product. The denominator of the improper fraction remains the same as the original denominator.
Denominator Stays the Same
The denominator of the improper fraction will always be the same as the denominator of the fractional part of the mixed number.
This rule reminds us that when we convert, we are just reorganizing how we count the parts, not changing the size of the parts themselves. For example, if you have 'halves', your improper fraction will still be i...
