Improper fractions
Converting improper fractions to mixed numbers.
Making percents
Making percents from fractions. If you can't make an equivalent fraction where the denominator is 10 or 100, you have to divide! (step 4)
Adding fractions
Never add the denominator! When your denominators are the same, you can add the numerator. Don't forget to simplify!
Mixed Numbers to improper Fractions
Multiply your denominator by your whole number.
Add this to your numerator.
This number is your new numerator; the denominator stays the same.
