What patterns do you see in this string. Describe how you see in this string. Can you find 3 or more?
Todays test asked 1/2 +1/3 does not equal 2/5. What evidence did you use to convince me?
Leave a comment. Thanks (58 comments yesterday. Lets have more today.

1) one pattern is that all fractions are unit fracshons. Another pattern is that 1/of 6 is 3, 1/4 of 12 is 3, and 1/8 of 24 is 3. Another pattern is that teh first three equals go down by half.
2) That is classified information and you are in no position to know that. I'm just kidding. I did the addition correct and proved i did the addition correct.
[1.a]the fractions are all unit fractions
[1.b] the first three answers are 12, 6, and 3. 3 is half of 6, and 6 is half of 12 because the fractions are getting half as small each time. From 1/2 to 1/4 to 1/8.
[1.c]
1/8 of 24=3
1/4 of 12=3
1/2 of 6=3
they all equal 3 because the way they change, cancels each other out the equal 3.
eg. 1/8x2=1/4 24/2=12
x cancels out / so the two questions,1/8 or 24 and 1/4 of 12 equal 3.
[2] 1/2+1/3 doesn't = 2/5 because if we turn 1/2 and 2/5 both into fractions out of 10,
1/2=5/10
2/5=4/10
then 5/10 is already larger than 4/10 and if you add more to 5/10 (1/2), it's only going to get larger and larger than 4/10 (2/5)
The first pattern, I see is the the first three go down by three`s eg. 12, 6, 3. The next pattern is the fractions are in unit fractions.
first pattern go down by halves 12, 6, 3
and the next pattern is unit fractions
1.a) one pattern i see in this string is that in the first three questions, the answers go down by halves like 6 is half of 12 and so on...
1.b) all fractions are unit fractions
1.c)1/2 of 6=3 and 1/4 of 12=3
you double the denominator 1/2 to 1/4 and then you doubled 6 to 12..so they should equal the same number, 3.
2)evidence i use is that u have to find the least common denominator(LCD) to add fractions.
i see it the first ones go down by threes, then the second pattern is unit practions, and the obvious one is the denominatro is 24
1]one pattern i see is that the denoominator of the fraction is divided into the whole number. like 1/2 of 6. you just divided 2 into six and the anwser is 3.
a]its all fraction units
2] the evidence i used is to find the lowest common denominator of the fractions. so then you just find the number that both 2 and 3 go into.
homework !/
i noticed that the first three are like halves of everything like for ex. a half of 24 is 12 and half of 12 is 6 and half of 6 is 3 and also i noticed that they are all unit fractions :)
