PURPLE - indicates a key term. (it would be best to remember this).
The first thing Mr. Backe wanted us to do was a question that looked like this:
We had to insert a sign in the middle that made the statement true. ( > is greater than, < is less than, = is the same.) First you would need to find the lowest common denominator (LCD) How you do that, is by multiplying the two denominators. So .. 7 (9) = 63. 63 would be the LCD. Remember, what you do to the bottom, you do to the top. <-- (Remember this for ratios later on.) Now you need 3 (9) = ? and for the other fraction 4 (7) = ?. The first answer would be 27 and the second one would be 28. Put all of the answers together and it would be WAY easier to compare. Your end result should look like the second picture. Why does this work? Because the fractions on the left and the fractions on the right are equivalent fractions. The only difference is that one is showed in simplest form.
Next, he wanted us to find numbers that fit in between 0.3 and 0.4. Also for 0.25 and 0.45. The number 0.35 would fit in between for both. A LOT of numbers would fit in between. An infinite amount of numbers. Meaning the list is endless. Mr. Backe also wanted to know which has more numbers in between. We all know it has an inifinite amount in between, BUT what we had to do was find the range of the numbers. You find range by subtracting the smallest number from the biggest number. So .. 0.4 - 0.3 = 0.1. And 0.45 - 0.25 = 0.2. The second set would have more numbers because it has a higher range. Remember, even if there is an infinite amount of numbers in between, the one with the larger range would have even more than that.
PS. At the end of class he gave us 3 signs. %, ¢, and $. What do these all have in common? Percent, 1 cent, 100 cents. Hmm, CENTS. They all have the word cent in it, which if you didn't know means 100.

FIRST TO COMMENT! Great job Dean! You did a great job with the whole "Lowest commom denominator" thing! The only thing that I would suggest for next time is maybe to add a bit more color to make your post more "COLOURFUL", you know, so that it stands out more.
haha alriht, i didnt want to over-exaggerate on the colours because i did that last year and Mr. Harbeck called it skittles, but for sure i'll work on it standing out. Thanks! :D
GOOD JOB DEAN! You used purple!(: Haha, anyways, I like your pictures and good job explaining. Did Mr. Harbeck really call it skittles? HAHA. Hm, instead of using more colours next time, you could use what you did and just bold them? I guess that would make it stand out more. Good job again! (:
Great job! You explained what we did in class very well. I'm not sure if you forgot but when you said > means greater than, you didn't say < means less than. But like I said, great job!
Dean, last time I checked 28 is more than 27?? Otherwise good job. Better late than never I guess.
Dean! Good Job! You explained everything well, except..your whole scribe is purple.O__O You might want to try alternating colours next time.
HAHA, woops.
i fixed the number exchange Backe, and joseph, the ( <, >, = ) thing kept on messing up my colour codes. Purple stands for important remember!
heey heey ! sorry for the late comment dean. i went on the blogger before to check out what's for homework and didnt comment because of firefox, sheeesh -_-. aannyywwhhhhhoo, i like your colors (PURPLE FTW!) but i agree with kara next time use different colors too to make it more fascinating but not too much ecause it WILL look like skittles, trust me been there, done that. you explained everything pretty and well and i think that you did an awesome job (: i used to say this last year in the scribe comments - KOODOS! :D. thanks for the hw again and keep up the good work !
Great job Dean! I like how you used purple as a colour! I think maybe you should have added more colour in the pictures even though they are just numbers. Anyways, Great job again!!
