Quiz Tomorrow!

Hello mathlings! This is just a reminder that tomorrow's quiz is going to include the following concepts:

Greatest Common Factor (GCF)

Least Common Multiple (LCM)

Equivalent Fractions

Simplest Form

Comparing and Ordering Fractions

Please study your notes tonight. You will need to use prime factorization to find both the GCF and LCM for some of the problems. A few reminders:

* When finding the GCF through prime factorization, the common factor that "matches" MUST be found in ALL of the numbers you are breaking down.

* When finding the LCM through prime factorization, the common factor that "matches" needs only to be found in TWO of the numbers you are breaking down to be considered a match and used once. It does not need to be found in all of the numbers you're breaking down.

* In order to compare and order fractions, all of the fractions must have the same denominator. Then, compare using the numerators. In order to change the fractions to equivalent fractions with the same denominator:

1. Find the Least Common Denominator (LCD).
2. Change the fractions to equivalent fractions using the LCD.
3. Ask: How could I get from my original denominator to the new denominator? Then, multiply the numerator by whatever you would multiply the denominator.

Again, please, please, please study your notes! We take them for a reason :) Good luck and happy studying!
