Hello, 905. This post will talk about most of the things we talked about in class.
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.

JOURNAL! Make sure your completing this daily, that's what the scribes are for! Anyways, sorry for this scribe being late, but comment and tell me if i made any mistakes! Next scribe will be, -DRUM ROLL- MELISSA! Have fun doing your scribe. Good job 905 for all the hard work we've been doing this whole time.
