As you know, there is a test this Friday and again on Tuesday. I distributed another study guide today during class (see me if you lost yours or didn't get one for some reason) that includes the following notes:

__Converting Fractions to Decimals and__

__Decimals to Fractions__

To
convert from a fraction to a decimal:

·
Multiply the denominator so it becomes a 10 or 100 and change it to a
decimal

·
Divide the numerator by the denominator (you may need to use a
repeating bar)

To
convert from a decimal to a fraction:

·
Say the decimal and turn it into a fraction then simplify

__Compare and Order Fractions__
·
Use common denominators to compare or order fractions

·
Cross multiply to compare fractions

__Percent__
·
Convert fractions to equivalent fractions over 100

__Probability & Ratio__
·
Write ratios in three forms, with a colon, using the word “to” and as a
fraction

·
Put ratios in lowest terms

__Proportion__
·
Set up proportions as two equivalent fractions

·
Make sure that labels match either vertically or horizontally

·
Use cross products (cross multiplication) to solve proportions

__Add, Subtract, Multiply and Divide Fractions__
Addition
and Subtraction:

·
Set up the problem vertically

·
Find common denominators and convert to equivalent fractions

·
Add or subtract numerators, keep denominators the same

·
Simplify your answer

Multiplication:

·
Make everything a fraction

·
Multiply numerators, multiply denominators

·
Simplify your answer

Division:

·
Make everything a fraction

·
Keep the first fraction, change the sign to multiplication, flip the
second fraction

·
Multiply numerators, multiply denominators

·
Simplify your answer

Friday's test will include most of the topics we have studied, and Tuesday's test will only include adding, subtracting, multiplying and dividing fractions and proportions. Keep up the good work and keep your eyes open for additional posts with games to help you prepare for the test and photographs from class.

By the way, we passed 40,000 views on the blog! Thanks for visiting the site and participating in the blog! I hope that we get to 50,000 soon!

Homework for tonight is to study for the math tests!
