You should really try to figure this out by yourself, but anyway:

amount discount = $b \cdot d$
$b$=beginning price
$d$=percent discount (in decimal form)

decimal to fraction: example: $0.5=\frac{5}{10}=\frac{1}{2}$
or
$0.25=\frac{25}{100}=\frac{1}{4}$

equivalent fractions with like denominators: turn the decimal into a fraction and don't simplify.

price after discount = $b \cdot (1-d)$
$b$=beginning price
$d$=percent discount (in decimal form)

Ratios can be written in three ways:

1:2
1/2
1 per 2 (1 for every 2)

Ordering fractions: this stuff is too easy for me to help on, PAY ATTENTION IN CLASS!!!!!

to find the percent of a fraction make the denominator of the fraction 100 and the numerator becomes the percent.
