# Math Help - Grade six testing is tomorrow

1. ## Grade six testing is tomorrow

Oh goodness, grade six testing is tomorrow and I need this information by tomorrow at 7:00 a.m.And I got 50% on my last test Please help.

How to find the discount price,
How to change a decimal to a fraction,
Write equivalent fractions with like denominators,
Find out the unit rate,
Find the sale price (e.g. \$24.75-20% off)
Write a ratio in 3 ways
Order fractions (improper, proper and mixed numbers)
Calculate the percent of fractions

If I dont get help Im DOOMED!!!!!

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)

3. ## More

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.

4. Thank you for helping, but the stuff oyu didnt answer, is the stuff that I dont understand!
