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!

Infographic

Here's a great infographic from Long Beach Unified School District that illustrates how to turn a mixed number into an improper fraction:

Circumference Visuals

Hey everyone! We will be reviewing circumference tomorrow. Here are some visuals for study (source: WikiHow):

Dividing Decimals by Decimals help

Study for quiz on Monday - decimals divided by decimals. This is a great link:

Also, look through your notes and through chapter 4 in the text. Look over the assignment we did on Wednesday and the notes you took during review on Thursday. There will not be retakes for this quiz.

Dividing Decimals by Decimals

Hello all! I just wanted to say thanks again to Khamal for teaching us the lattice method for multiplication today. Khamal, you did an AMAZING job!

Tomorrow we return to dividing decimals by decimals. Just like for last night's homework, remember to move the outside decimal all the way to the right in order to make it a whole number (then, don't forget to move the decimal on the inside the same # of times!). We'll be doing a set of ten questions in class that I will collect as an assessment. You will be able to use your notes.
